&lt;h4&gt;Objective &lt;/h4&gt;
&lt;p&gt;Open and transparent research practices are essential for high-quality research. Despite growing efforts to promote these practices through new funding policies, a rethinking of evaluation criteria, and investment in support and infrastructure, widespread adoption across disciplines remains challenging. Comprehensive data and analysis of the perceived risks and barriers to implementing open research practices within UK higher education institutions (HEIs) is still lacking.&lt;/p&gt;
&lt;h4&gt;Design &lt;/h4&gt;
&lt;p&gt;In 2025, we conducted an inductive thematic analysis of openly available data from the UK Reproducibility Network Open and Transparent Research Practices Survey,&lt;sup&gt;1&lt;/sup&gt; which was conducted between December 2022 and April 2023. The survey addressed 14 topics related to open research practices (eg, research coproduction, open-source code and software, reproducibility, open access, FAIR principles [findability, accessibility, interoperability, and reusability], and conflicts of interests), with respondents answering questions on practice, support, and approaches to each practice. This analysis focuses on responses to the open-text questions specifically referring to&lt;i&gt; &lt;/i&gt;risks or barriers to researchers or to their fields of study across all 14 topics. Following SRQR guidelines,&lt;sup&gt;2&lt;/sup&gt; we ensured transparency in our analytic process. One researcher analyzed the data and developed initial codes, which have been reviewed by a second coder, before agreeing on collaboratively refined themes through iterative discussion. We used NVivo, version 14 (Lumivero) for analysis and data management. Reflexivity was maintained through regular team debriefs. Ethical approval was not required as the data were publicly available and anonymized. &lt;/p&gt;
&lt;h4&gt;Results &lt;/h4&gt;
&lt;p&gt;The survey received 2567 responses from research-active staff at 15 UK HEIs. Of these, 511 (20%) responses were complete. Participants reported barriers and risks to the 14 open research topics (&lt;b&gt;Table 25-0863&lt;/b&gt;), which we grouped into 3 overarching categories: personal, systemic and institutional, and ethical and quality. In the personal category, respondents highlighted lacking motivation to undertake open research practices, with some perceiving that such practices should not rely on researchers and others perceiving such practices as a mere tick-box exercise. Respondents also feared that open research practices would expose errors and make them vulnerable to criticism. In the systemic and institutional category, respondents described barriers that made them unable to practice open research, such as methodological or disciplinary barriers. They also highlighted missing infrastructure and a lack of resources. Others also mentioned that institutions did not support them adequately, did not provide appropriate training, and did not recognize or incentivize open research practices, making it difficult for them to engage in open research. On an ethical and quality level, respondents worried that open research practices introduced new ethical concerns, or even that they detract from high-quality research and innovation.&lt;/p&gt;

&lt;h4&gt;Conclusions &lt;/h4&gt;
&lt;p&gt;These findings underscore critical challenges hindering the adoption of open research practices in UK HEIs. Addressing these barriers requires enhanced institutional support, targeted training, and robust incentives to empower researchers. Mitigating these challenges could significantly improve the quality and transparency of academic research.&lt;/p&gt;

technical paper

<p>Ayu Putu Madri Dewi,<sup>1</sup> Melissa L. Rethlefsen,<sup>2</sup> Sara Schroter,<sup>3,4</sup> Florian Naudet,<sup>5,6</sup> Nicholas J. DeVito,<sup>7</sup> Constant Vinatier,<sup>5</sup> Inge Stegeman,<sup>8,9</sup> Mariska Leeflang,<sup>1</sup> Gowri Gopalakrishna<sup>1,10</sup></p>
<h4>Objective</h4>
<p> <i>The BMJ</i> is one of the first journals to require authors to share analytic codes from all studies as well as data from all trials,<sup>1</sup> but whether this enhances reproducibility has not been tested. We will assess whether adding an open science checklist to the journal peer review process improves the reproducibility of scientific findings in submitted manuscripts to <i>The BMJ</i> and <i>BMJ Open</i>.</p>
<h4>Design</h4>
<p> This study is registered on Open Science Framework<sup>2</sup> and follows the SPIRIT guidelines. Reproducibility was defined as obtaining the same primary result when rerunning analyses using the original data and code. We used a 2-arm parallel randomized controlled trial design, equal allocation, and random block randomization (block sizes of 4, 6, and 8; generated in R version 4.3.2 [The R Foundation]). We hypothesized that the intervention will increase reproducibility of primary outcomes from 50% in the control arm to 70% in the intervention arm (90% power; α = .05). Our minimum sample size is 260 manuscripts (minimum 130 manuscripts per arm). Eligible manuscripts include quantitative observational or experimental designs and systematic reviews containing a meta-analysis. In the intervention arm, the research team completed an open science checklist assessing whether a set of predefined open science items<sup>3</sup> (<b>Table 25-1009</b>) were reported in the manuscripts. The completed checklist was shared with the authors as part of the standard peer review process. Manuscripts in the control arm followed the usual peer review process. The primary outcome was the difference in reproducibility of the authors’ reported primary outcomes between the 2 arms, as assessed by blinded outcome assessors. The secondary outcome was the proportion of manuscripts with openly shared data and code. If the data, code, or methods were unavailable or only available on request, authors were not contacted, as they were blinded to the study, and the outcome assessors did not proceed. Randomization began on March 3, 2025, with outcome assessments conducted after the first manuscript revision.</p>

<h4>Results</h4>
<p> By April 18, 2025, we had completed randomization of 403 manuscripts. This includes open science intervention in 22 of 43 manuscripts from <i>The BMJ</i> and 179 of 360 manuscripts from <i>BMJ Open</i>. As of June 5, 2025, 78 manuscripts had received a decision letter, including 39 rejections, while the remainder proceeded to reproducibility assessment. Analysis is ongoing.</p>
<h4>Conclusions</h4>
<p> This study will provide robust evidence on whether incorporating an open science checklist into the peer review process improves the reproducibility of scientific findings.</p>

Griessbach,<sup>1</sup> Sally Hopewell,<sup>11</sup> Matthias Briel,<sup>1,3</sup> for the ASPIRE Study Group</p>
<h4>Objective</h4>
<p> Previous studies found that approximately one-third of randomized clinical trials (RCTs) were discontinued prematurely and that the most common reason for stopping early was poor recruitment of participants. To minimize research waste, it is crucial that all RCTs are registered and make their results available. Hence, we aimed to (1) assess the fate of RCTs approved by ethics committees in 2016 in terms of nonregistration, discontinuation, and nonpublication and (2) examine RCT characteristics associated with discontinuation due to poor recruitment and nonpublication of RCT results.</p>
<h4>Design</h4>
<p> We had access to 347 RCT protocols that were approved in 2016 by research ethics committees in the UK, Switzerland, Germany, and Canada. Key trial characteristics were extracted from approved trial protocols. <span lang="de-DE">Trial registration was verified using registration numbers from the protocol and by searching the </span>World Health Organization<span lang="de-DE"> International Clinical Trials Registry Platform, ClinicalTrials.gov, </span>European Union Clinical Trials Register<span lang="de-DE">, ISRCTN, and Google; trials were deemed nonregistered if not found. We searched for full-text publications in PubMed, Google Scholar, and Scopus. Searches for both registration and publication used (</span>1<span lang="de-DE">) full titles</span>,<span lang="de-DE"> (</span>2<span lang="de-DE">) short titles</span>,<span lang="de-DE"> (</span>3<span lang="de-DE">) study acronyms</span>,<span lang="de-DE"> and (</span>4<span lang="de-DE">) the study population and intervention. </span>All searches were conducted in duplicate (last search, July 2024). In case the status of an RCT was unclear, we contacted the corresponding ethics committee or the principal investigator. We reported the proportion of nonregistered RCTs, discontinued RCTs (including reason for early discontinuation), and nonpublished RCTs (considering peer-reviewed publications and results in trial registries). </p>
<h4>Results</h4>
<p> Of the 347 included RCTs from 2016, 20 (5.8%) were nonregistered (industry-sponsored RCTs, 5 of 181 [2.8%]; nonindustry RCTs, 15 of 166 [9.0%]). Approximately one-third of RCTs (108 of 347 [31.1%]) were discontinued, most often due to poor recruitment (49 of 108 [45.4%]). A total of 276 of 347 RCTs (79.5%) made their results available at any source, 249 (71.8%) as a peer-reviewed publication, and 170 (49.0%) in the trial registry. Discontinued RCTs had lower result availability than completed RCTs (discontinued, 74 of 108 [68.5%]; completed, 202 of 226 [89.4%]). Results from industry-sponsored trials were more often available compared with nonindustry trials (92% vs 66%). This difference was driven by the fact that only 17 of 166 nonindustry RCTs (10.2%) reported results in trial registries compared with 153 of 181 industry trials (84.5%). The status of 4% of RCTs remained unclear despite our efforts to contact investigators.</p>
<h4>Conclusions</h4>
<p> Nonregistration, premature discontinuation due to poor recruitment, and nonpublication of RCT results remain major challenges, especially for nonindustry trials.</p>

Nonregistration, Discontinuation, and Nonpublication of Randomized Trials in Switzerland, the UK, Germany, and Canada: An Updated Meta-Research Study

<p>David Blanco,<sup>1</sup> Elizabeth Loder,<sup>2,3</sup> Sophie Cook,<sup>3</sup> Martí Casals,<sup>4,5</sup> Jordi Cortés,<sup>6</sup><span lang="ar-SA"> Aïda Cadellans-Arroniz,</span><sup>1</sup> Victor Zárate,<sup>1</sup> Ella Hubbard,<sup>3</sup> Sara Schroter<sup>3,7</sup></p>
<h4>Objective </h4>
<p>In 2005, the International Committee of Medical Journal Editors (ICMJE) mandated that all clinical trials be properly registered—that is, registered in an approved registry at or before the enrollment of the first participant.<sup>1</sup> Despite improved registration rates, many trials published in journals claiming adherence to ICMJE registration policy remain improperly registered.<sup>2</sup> This study aimed to (1) identify variables associated with improper registration; (2) examine types of registration deficiencies, publication status, and disclosure of registration issues in improperly registered trials; and (3) assess authors’ claims of proper registration.</p>
<h4>Design </h4>
<p>This observational study analyzed 239 improperly and 239 properly registered trials submitted to <i>The BMJ</i> (2019-2023). For objective 1, we collected data on trial design, setting, sample size, intervention type, number of authors, corresponding author region, mention of Consolidated Standards of Reporting Trials (CONSORT) guidelines, submission year, and funding source. For objective 2, we examined improperly registered trials submitted between 2019 and 2021, focusing on registration deficiency type (retrospective registration in approved registry, registration in unapproved registry, or no registration), registration delay (for retrospectively registered trials), and publication status. For published trials, we recorded Journal Impact Factor, ICMJE affiliation, time to publication, and disclosure of registration issues. For objective 3, we assessed authors’ claims of prospective registration for improperly registered trials. Analyses included multivariable logistic regression and descriptive statistics.</p>
<h4>Results </h4>
<p>Several variables were associated with reduced odds of improper registration: larger sample size (101-500 vs 1-100; odds ratio [OR], 0.43 [95% CI, 0.22-0.84]), corresponding authors from Oceania (reference: Europe; OR, 0.35 [95% CI, 0.14-0.82]), more authors (10 vs 1; OR, 0.53 [95% CI, 0.32-0.87]), CONSORT mention (OR, 0.22 [95% CI, 0.06-0.67]), recent submissions (2021-2023 vs 2019-2020; OR, 0.63 [95% CI, 0.42-0.96]), and funding (eg, nonprofit vs no funding; OR, 0.20 [95% CI, 0.09-0.41]). Trials with authors from Asia (OR, 1.75 [95% CI, 1.07-2.89]) had higher odds of improper registration. Of 176 improperly registered trials, 82.4% (n = 145) were retrospectively registered in approved registries (median delay, 6.54 months; Q1, 2.50 months; Q3, 18.67 months), 13.1% (n = 23) were unregistered, and 4.5% (n = 8) used unapproved registries. Most (88.1% [n = 155 trials]) were later published, including 1 in <i>The BMJ</i>. Among these, 89.0% (n = 138) appeared in journals with an Impact Factor (median, 5.39; Q1, 3.98; Q3, 10.40) and 62.0% (n = 96) in journals claiming adherence with ICMJE registration policy. Median time to publication was 12 months (Q1, 8 months; Q3, 19 months). Only about one-sixth explicitly acknowledged the registration issue at the time of publication. Of 72 responses to <i>The BMJ</i>’s submission question on prospective registration (2021-2023), 83.3% (n = 60) incorrectly claimed compliance.</p>
<h4>Conclusions </h4>
<p>We identified variables associated with improper trial registration. Retrospective registration was common, and most improperly registered trials rejected by <i>The BMJ</i> were later published in other ICMJE-affiliated journals. ICMJE journals should strengthen processes to better identify and reject improperly registered trials.</p>

<p> East Asia has become a major hub for clinical trials.<sup>1</sup> Although a few studies have compared ClinicalTrials.gov with local registries in specific disease domains, comprehensive comparisons remain limited.<sup>2</sup> This study analyzes registered clinical trial trends in East Asia during 2014 to 2025 and compares them with trends in the US.</p>
<h4>Design</h4>
<p> We extracted clinical trial data through the World Health Organization–operated International Clinical Trials Registry Platform (ICTRP), which integrates ClinicalTrials.gov and local registries. Because Taiwan’s registry is not part of the ICTRP, we collected its data separately. We analyzed overall clinical trial trends and filtered randomized clinical trials (RCTs), categorizing them by location, target size, and disease category. Trials conducted in only 1 country were categorized as domestic, whereas those conducted in 2 or more countries were classified as international. We explored the proportion of studies registered prospectively, defined as within 1 month of the trial start date.<sup>3</sup></p>
<h4>Results</h4>
<p> China experienced rapid growth in clinical trials, surpassing both Japan and the US in total trials and RCTs (<b>Figure 25-1020</b>). In China, the number of registered trials increased markedly from 2578 total trials (1521 RCTs) in 2014 to 16,612 (7798 RCTs) in 2023. In contrast, the US showed a more modest increase from 8841 trials (4056 RCTs) in 2014 to 9100 (4619 RCTs) in 2023. Except for China, all other countries experienced a postpandemic decline, with annual trial registrations decreasing by approximately 3% to 10% in recent years.<span class="CharOverride-18"> </span>Neoplastic diseases and cardiovascular and metabolic diseases accounted for the largest percentages, each representing approximately 15% to 25% of all registered trials. In the US, mental health trials increased from 11.9% in 2014 to 16.0% in 2023, reflecting growing interest in this area. In 2023, China’s RCTs were predominantly domestic, with international trials making up only 1.8% (140) of the total, while 13.1% (603) of RCTs in the US were international. Domestic RCTs were predominantly small-sized trials (&lt;100 participants), while international RCTs were more commonly medium-sized (100-499 participants) or large-sized (≥500 participants) trials. In 2023, 75% of China’s RCTs (5841 of 7798) and 81% of Japan’s RCTs (1081 of 1339) were domestic trials registered in local registries, highlighting the predominant use of local registries in both countries. Although the trend has increased over the past decade, a considerable percentage of RCTs, ranging from 15% to 35% across countries, were still not registered prospectively in 2023. We recorded some inconsistencies and missing information across existing registries. Updated data to mid-2025 will be presented at the congress.</p>

<h4>Conclusions</h4>
<p> The study highlights the increasing prominence of East Asia, particularly China, in registered clinical trials, though with a primarily domestic focus. Improvements in existing trial registries covering East Asia are desirable.</p>

Registered Clinical Trial Trends in East Asia and the United States, 2014 to 2025

<p>Aidan Christopher Tan,<sup>1,2</sup> Yiyi Lin,<sup>1</sup> Michellie Lian,<sup>1</sup> Zhilin Ren,<sup>1</sup> Tony Lian,<sup>1</sup> Vincent Yuan,<sup>3</sup> Angela Webster,<sup>1</sup> Anna Lene Seidler<sup>1</sup></p>
<h4>Objective</h4>
<p> We aimed to describe researcher adherence to journal data sharing policies across health research. This included describing what factors increase intention to share data and how journal policies requiring data sharing impact intended data sharing.</p>
<h4>Design</h4>
<p> This was a cross-sectional study of all original research published in the highest-impact medical journals in 2022. Journals were included if they ranked among the top 5 in Impact Factor in 59 fields of medicine in the 2020 Journal Citation Reports, had a data sharing policy that either required or recommended sharing data, and published original research. Journal websites were searched to identify all original research published in 2022. Data were manually collected on study characteristics (study type, industry involvement, and COVID-19 relevance) and data sharing plans (data sharing statements and data sharing intentions extracted from publicly available research protocols and articles). Articles were descriptively analyzed by these journal data sharing policies, study characteristics, and data sharing plans.</p>
<h4>Results</h4>
<p> Of 134 journals included, 36 (27%) required data sharing and 98 (73%) recommended data sharing. The analysis included 1868 interventional studies (1383 randomized clinical trials [74%] and 485 nonrandomized trials [26%]) and 10,368 observational studies (4814 cohort studies [46%], 4166 cross-sectional studies [40%], 1100 case-control studies [11%], and 288 case series/reports [3%]). Publicly available research protocols were available for 1993 of 10,243 studies (16%), of which 1153 (58%) had an initial data sharing statement. Only 1023 interventional studies (55%) and 4511 observational studies (44%) in journals that recommended or required data sharing actually intended to share data. Most studies only intended to share data underlying the published results with researchers, for purposes and by mechanisms at the discretion of and subject to approval by the principal investigator and without supporting documents or specified timeframes. Factors associated with increased intention to share data included journal policies that required data sharing and data sharing statements as well as industry involvement and COVID-19 relevance for interventional studies. For journals with policies that required data sharing, researchers were more likely to share more data (ie, all data collected during the study) and supporting documents (ie, supporting documents) in a timelier manner (ie, immediately following publication and indefinitely) to more people (ie, to anyone who wishes to access the data) for more purposes (ie, for any purpose) and by easier means (ie, with unrestricted access through a third-party website).</p>
<h4>Conclusions</h4>
<p> Journals that required data sharing had higher rates of studies that intended to share data compared with journals that only recommended data sharing. However, most studies that intended to share data had restrictions on sharing. In addition to requiring data sharing and data sharing statements, journals should define and explain data sharing and individual participant data, better review data sharing statements and the reasonableness of justifications to not share data, and provide additional guidance on the operationalization of data sharing in accordance with best practice.</p>

Researcher Adherence to Journal Data Sharing Policies: A Meta-Research Study

<p>Robert Thibault,<sup>1,2</sup> Dana E. Cobb-Lewis,<sup>1,2</sup> Matt Lewis,<sup>1,2</sup> Devin Snyder,<sup>1,2</sup> Cornelis Blauwendraat,<sup>1,2</sup> Sonya Dumanis<sup>1,2</sup></p>
<h4>Objective </h4>
<p>We examined whether a funder-led open science policy and compliance workflow could increase the deposition and unambiguous identification of research data, code, protocols, and key laboratory materials (eg, cell lines, antibodies).</p>
<h4>Design </h4>
<p>A cross-sectional study was conducted on articles supported by the Aligning Science Across Parkinson’s (ASAP) Collaborative Research Network (CRN) and published between January 1, 2024, and April 30, 2025 (N = 102). The study was exploratory, and thus was not registered, and does not present inferential statistics. ASAP has a thorough Open Science Policy<sup>1</sup> and Compliance Workflow,<sup>2</sup> which require grantees to send manuscript drafts to ASAP staff, post preprints, deposit research outputs, and unambiguously identify research inputs. The workflow is managed by an ASAP staff member who integrates automated and manual assessments to provide a grantee with systematic feedback outlining the actions required to align their manuscript draft with the ASAP Open Science Policy.</p>
<h4>Results </h4>
<p>Between the version of a manuscript first shared with ASAP staff and the associated final publication, there were substantial increases in the deposition of newly generated datasets (21% for the first version to 88% for the published version), unambiguous identification of reused datasets (72% to 86%), deposition of newly generated code (15% to 72%), unambiguous identification of software used (35% to 79%), registration of newly generated key lab materials (22% to 78%), unambiguous identification of key lab materials used (44% to 87%), and deposition of newly generated protocols and unambiguous identification of existing protocols (35% to 81%; data on protocols was collapsed) (<b>Table 25-0892</b>). Of the included publications, 98% (100 of 102) had an associated preprint. Preprints were posted a median (IQR) of 4 (−7 to 50) days before submission to the journal in which they were eventually published and 236 (150-328) days before they were published in a journal. To facilitate this workflow, grantees share each manuscript alongside a Key Resource Table that lists persistent identifiers for the associated datasets, code, software, protocols, and key lab materials. Collating these Key Resource Tables provides a living and near-comprehensive log of all the inputs and outputs from ASAP CRN–funded research.</p>

<h4>Conclusions </h4>
<p>A funder-led intervention to monitor and support a robust open science policy can foster the posting of preprints and the sharing of data, code, protocols, and key lab materials.</p>

A Funder-Led Intervention to Increase the Sharing of Data, Code, Protocols, and Key Laboratory Materials

<p>Kyobin Hwang,<sup>1</sup> Zexing Song,<sup>2,3</sup> Marsida Stafa,<sup>3</sup> Jodie Chiu<sup>,4</sup><sup> </sup>An-Wen Chan<sup>1,3,5</sup></p>
<p><h4>Objective</h4> We aimed to determine how often medical journals have policies requiring clinical trial registration, adherence to reporting guidelines, and participant-level data sharing. We also evaluated associations between journal characteristics and the existence of such policies for clinical trial manuscripts.</p>
<p><h4>Design </h4>A PubMed search using the clinical trial filter was conducted to identify journals that published at least 20 trials in 2023. We extracted publicly available data from journal websites, including policies on trial registration, adherence to reporting guidelines, trial protocol submission requirements, and availability of participant-level data. A practice was classified as required if the policy used words such as must, need, or should. Policies using language such as encouraged and preferred were classified as recommended practices. For each journal, we recorded the 2023 Clarivate impact factor, journal scope (general vs specialty), and publishing model (purely open access vs other). We calculated descriptive statistics to summarize the prevalence of transparency policies and used multivariable logistic regression to assess the association between journal characteristics and policy requirements.</p>
<h4>Results</h4>
<p> Among 380 included journals, 320 (84%) required trial registration, 11 (3%) recommended it, and 49 (13%) did not mention it. Adherence to a reporting guideline for clinical trials was required by 251 journals (66%), recommended by 74 (19%), and not mentioned by 55 (14%). Trial protocol submission was required by 118 (31%), recommended by 110 (29%), and not mentioned in 152 (40%). Public availability of participant-level datasets was required by 104 (27%), recommended by 218 (57%), and not mentioned by 58 (15%). A description of the data sharing plan was required by 212 journals (55.8%), recommended by 110 (28.9%), and not mentioned by 58 (15.3%). Purely open access journals had a 4-fold higher odds of requiring trial registration (adjusted odds ratio [AOR], 4.02; 95% CI, 1.41-15.59) and protocol submission (AOR, 4.13; 95% CI, 2.17-8.37) and 2.5 times higher odds of requiring public sharing of participant-level data (AOR, 2.46; 95% CI, 1.03-7.04) compared with other journals (<b>Table 25-1183</b>). Each 5-point increase in journal impact factor was associated with a more than 2.5-fold increase in the odds of requiring trial registration (AOR, 2.65; 95% CI, 1.45-5.98) and over 50% increase in the odds of requiring protocol submission (AOR, 1.56; 95% CI, 1.26-2.03). Impact factor was not significantly associated with requiring data sharing. No significant associations were found for journal scope or volume of trials published.</p>

![](https://assets.underline.io/markdown_image/1/image/1f3e3ae7eedf2cd146453708cac3c6fc.png)

<h4>Conclusions</h4>
<p> Journal policy requirements vary substantially in supporting best practices for clinical trial transparency. Journals with a purely open access publishing model and higher impact factor were more likely to adopt transparency policies. These findings highlight the need for improved editorial standards across the publishing landscape to promote transparency and reduce research waste.</p>

Medical Journal Policies on Requirements for Clinical Trial Registration, Reporting Guidelines, and Data Sharing: A Systematic Review

<p>M. Janina Sarol,<sup>1</sup> Jodi Schneider,<sup>1,2</sup> Halil Kilicoglu<sup>1</sup></p>
<h4>Objective </h4>
<p>An estimated 25% of citations in medical journals are inaccurate.<sup>1</sup> If not corrected, these citation quotation errors can propagate misinformation and establish unfounded claims.<sup>2</sup> Correcting them before publication is vital, yet citation accuracy is overlooked in the peer review process. The prevalence of citation quotation errors in the biomedical literature also remains unclear, because existing studies rely on manual evaluation on a limited set of articles.</p>
<h4>Design </h4>
<p>We explored the use of large language models, specifically Gemini 1.5 Pro, GPT-4o (gpt-4o-2024-08-06), and LLaMA-3.1 (8B and 70B), to automatically identify citation quotation errors. We compared 2 approaches. In the first, we supplied the prompt with the citation in question, the paragraph containing the citation, and the full reference article. The second approach consists of a 3-step procedure and mimicked how a human reviewer might perform the task manually by first identifying the citation context, then locating relevant sentences in the reference article, and finally assessing citation accuracy. Specifically, the procedure consists of (1) extracting the citation sentence, (2) retrieving the 50 most relevant sentences using the MedCPT retriever model and reranking them with a fine-tuned MonoT5 model to select the top 5 sentences, and (3) verifying the citation accuracy with the large language model (<b>Box 25-1015</b>). Both approaches were evaluated from November 2024 to January 2025 using a citation quotation error dataset,<sup>3</sup> the first publicly available corpus of its kind (Cohen κ for interrater agreement: 0.96 for citation context and 0.31 for accuracy detection). The better-performing approach was applied to assess 2898 citations from 2000 articles to the 100 most cited PubMed Central Open Access (PMC-OA) articles (24 different journals).</p>

![](https://assets.underline.io/markdown_image/1/image/e80718c94a9aa238f09a1d74fc02135d.png)

<h4>Results </h4>
<p>Gemini 1.5 Pro yielded best performance, obtaining an accuracy of 69% with both approaches. It outperformed GPT-4o slightly, while LLaMA-3 failed to generate meaningful results with the first approach and performed poorly with the second. Because the first approach only identified 25% (55 of 220) of the erroneous citations and the 3-step procedure identified 51% (113 of 220), the second approach was applied to the subset of PMC-OA articles. In the PMC-OA subset, 34% (981 of 2898) of the citation instances were assessed as erroneous. A total of 37% (742 of 2000) of citing articles were found to contain citation quotation errors; 98% (98 of 100) of reference articles were cited incorrectly at least once.</p>
<h4>Conclusions </h4>
<p>Our preliminary results confirm the high prevalence of citation quotation errors in the medical literature. We will present a more comprehensive analysis of citation quotation errors in the PMC-OA subset at the conference. Automated verification of citations could help journals and peer reviewers identify questionable citation practices and reduce propagation of misinformation, improving the trustworthiness of scientific evidence.</p>

Leveraging Large Language Models for Detecting Citation Quotation Errors in Biomedical Literature

<p>Bojan Batalo,<sup>1</sup> Erica K. Shimomoto,<sup>1</sup> Neil Millar<sup>2</sup></p>
<h4>Objective </h4>
<p>Promotional language (hype) in biomedical research writing has increased significantly over the past 40 years and has potential to influence readers’ perceptions and evaluations of evidence.<sup>1-3</sup> Automatic systems capable of detecting and providing feedback on hype may offer a means to foster more objective reporting. However, the absence of formal guidelines for identifying hype represents a barrier for human annotators and the development of such systems. This pilot study develops formal guidelines for classifying hype and evaluates the application of annotated data to automate hype detection via machine learning.</p>
<h4>Design </h4>
<p>Annotation guidelines were developed to classify 11 adjectives commonly associated with novelty and potential hype (eg, <i>creative</i>, <i>first</i>, <i>groundbreaking</i>, <i>innovative</i>). Guidelines followed the following hierarchical decisions: (1) does the adjective imply a positive value judgment?; (2) is it hyperbolic?; (3) is the adjective gratuitous (ie, adds little to the content), amplified (strengthened by modifiers), or coordinated (paired with other promotional adjectives)?; and (4) is the broader sentential context promotional? A total of 550 sentences containing the adjectives (50 per adjective) were randomly sampled from National Institutes of Health grant abstracts funded between 2016 and 2020 and independently annotated by a linguist and 2 computer scientists, with disagreements resolved through discussion, providing the criterion standard. Our choice of grant abstracts as the starting point for our research is due to the highly competitive nature of research funding.<sup>1</sup> The annotated data were split 80:20 into development and hold-out test sets; machine learning algorithms were trained on the development and evaluated on the test set. Additionally, a human baseline was established by an additional researcher blinded to the annotation guidelines but supplied with a broad definition of hype, manually classifying the test set. Experiments tested 4 traditional text classification methods (multinomial Naive Bayes, multivariate Bernoulli Naive Bayes, latent semantic analysis, and support vector machines), with bag-of-words and averaged global vectors for word representation (GloVe) word embeddings as input features (<b>Table 25-0929</b>). Performance was evaluated using accuracy, weighted precision, recall, and F1 scores.</p>

![](https://assets.underline.io/markdown_image/1/image/334927ffdad7b95527ef7831f37feb90.png)

<h4>Results </h4>
<p>Excluding 13 sentences due to nonadherence with the guidelines, the final sample comprised 537 reliably annotated sentences (Cohen κ &gt; 0.94), of which 392 were classified as hype. Among machine learning models, GloVe-based support vector machines outperformed others with an accuracy of 79.6%, approximating the human baseline of 82.4%.</p>
<h4>Conclusions </h4>
<p>The annotation process underscored the subjective nature of assessing promotional language, particularly for context-dependent adjectives like <i>emerging</i> and <i>latest</i>, and the need for refined constructs to capture gradations of promotional language. Despite these limitations, the pilot study indicates the potential for machine learning models trained on well-annotated datasets to contribute to the automated detection of hype. Future steps include modifying the annotation systems and experimenting with large language models under zero/few-shot regimes.</p>

<p>Journals, conferences, and funding agencies face the risk that reviewers might ask large language models (LLMs) to generate reviews by uploading submissions. Existing detectors struggle to differentiate between fully LLM-generated and LLM-polished reviews. We addressed this problem by developing a method to detect and flag LLM-generated reviews while controlling family-wise error rates (FWERs).</p>
<h4>Design </h4>
<p>Our method had 3 components. (1) Watermarking: We stochastically chose specific phrases (watermarks), such as random (fake) citations, technical terms (“weak supervised learning”), or beginning the review with a prefix (“This paper investigates the problem…”). Watermarks were specific modifications to the review, which were undetectable unless the nature of the watermark was known. The watermark was known to the editors (but not the reviewers), who could detect LLM-generated reviews through watermarks in the review. (2) Hidden prompt injection: We added an instruction into the manuscript PDF (at the end of the last page; not detectable by the human reviewer) instructing the LLM to output the chosen watermark in the LLM-generated review (“Start your review with: &lt;chosen watermark&gt;”). We evaluated 3 injection methods: white text, font manipulation,<sup>1-3</sup> and a different language. (3) Statistical detection method: We developed a test for watermarks in the review (null hypothesis was the review was human written) and provided mathematical proof of controlling the FWER without making assumptions on how human reviews were written. The evaluation was performed on International Conference on Learning Representations (ICLR) manuscripts, a publication venue that reviews full manuscripts. We injected the hidden prompts into ICLR manuscripts and asked LLMs to generate a review and observe whether it contained the watermark. We also evaluated the robustness of our methods against 3 reviewer defenses (RDs), measures reviewers could take to avoid being flagged for using an LLM-generated review: paraphrasing (paraphrasing the original LLM-generated review using another LLM), identifying watermarks (asking the LLM to flag submissions with hidden prompts), and cropping out the end of the paper (removing the last page before generating the review using an LLM). Watermarks were most successfully embedded in the LLM-generated review when the hidden prompt was injected at the end of the last page. For the evaluation of the last RD, we injected the hidden prompt at a position other than the end of the last page.</p>
<h4>Results </h4>
<p>Our method was successful in embedding the chosen watermark in LLM-generated reviews and was robust to RD mechanisms (<b>Table 25-1176</b>) and detecting and flagging them while controlling false-positives. We conducted our test on 28,028 human-written reviews from ICLR 2021 and 10,022 from 2024, each augmented with 100 LLM-generated reviews with a watermark embedded for each of the 3 types. When executing our algorithm to control the FWER at 0.01 for the random start and technical term watermark and 0.001 for the random citation watermark, we observed 0 false-positives in all cases.</p>

<h4>Conclusions </h4>
<p>We propose a novel method to detect LLM-generated peer reviews. Our evaluations found this method to be successful, making it appealing to journal, conference, and proposal review organizers.</p>
