The aim of this study was to test the usefulness of an infographic in the translation of knowledge about health information from a Cochrane systematic review to lay and professional populations in comparison to a plain language summary (PLS) and scientific abstract (SA). We conducted three parallel randomized trials with university students (n = 171), consumers (n = 99), and doctors (n = 64), to examine the effect of different summary formats of a Cochrane systematic review on the knowledge about health information presented in the review, reading experience, and perceived user-friendliness. In the trials involving students and doctors, an infographic was compared to a PLS and a SA, while in those with consumers, an infographic was compared to a PLS. We found no difference in knowledge between the infographic and the text-based PLS in any of the trials or in the whole participant sample. All three participant groups preferred the infographic and gave it higher ratings for reading experience (d = 0.48 in the overall sample) and user-friendliness (d = 0.46 in the overall sample). Although the infographic format was perceived as more enjoyable for reading, it was not better than a traditional, text-based PLS in the translation of knowledge about findings from a Cochrane systematic review.

In light of increasing calls for transparent reporting of research and prevention of detrimental research practices, we conducted a cross-sectional machine-assisted analysis of a representative sample of scientific journals’ instructions to authors (ItAs) across all disciplines. We investigated addressing of 19 topics related to transparency in reporting and research integrity. Only three topics were addressed in more than one third of ItAs: conflicts of interest, plagiarism, and the type of peer review the journal employs. Health and Life Sciences journals, journals published by medium or large publishers, and journals registered in the Directory of Open Access Journals (DOAJ) were more likely to address many of the analysed topics, while Arts & Humanities journals were least likely to do so. Despite the recent calls for transparency and integrity in research, our analysis shows that most scientific journals need to update their ItAs to align them with practices which prevent detrimental research practices and ensure transparent reporting of research.

To gain insight into changes of scholarly journals’ recommendations, we conducted a systematic review of studies that analysed journals’ Instructions to Authors (ItAs). We summarised results of 153 studies, and meta-analysed how often ItAs addressed: 1) authorship, 2) conflicts of interest, 3) data sharing, 4) ethics approval, 5) funding disclosure, and 6) International Committee of Medical Journal Editors’ Uniform Requirements for Manuscripts. For each topic we found large between-study heterogeneity. Here, we show six factors that explained most of that heterogeneity: 1) time (addressing of topics generally increased over time), 2) country (large differences found between countries), 3) database indexation (large differences found between databases), 4) impact factor (topics were more often addressed in highest than in lowest impact factor journals), 5) discipline (topics were more often addressed in Health Sciences than in other disciplines), and 6) sub-discipline (topics were more often addressed in general than in sub-disciplinary journals).

Preprint servers are online platforms that enable free sharing of preprints, scholarly manuscripts that have not been peer reviewed or published in a traditional publishing venue (eg, journal, conference proceeding, book). They facilitate faster dissemination of research, soliciting of feedback or collaborations, and establishing of priority of discoveries and ideas.1 However, they can also enable sharing of manuscripts that lack sufficient quality or methodological details necessary for research assessment, and can help spread unreliable and even fake information.2 Since 2010, more than 30 new preprint servers have emerged, yet research on preprint servers is still scarce.3 With the increase in the numbers of preprints and preprint servers, we explored servers’ policies, submission requirements, and transparency in reporting and research integrity recommendations, as the latter are often perceived as mechanisms by which academic rigor and trustworthiness are fostered and preserved.4

Background: Reviewers rarely comment on the same aspects of a manuscript, making it difficult to properly assess manuscripts’ quality and the quality of the peer review process. The goal of this pilot study was to evaluate structured peer review implementation by: 1) exploring whether and how reviewers answered structured peer review questions, 2) analysing reviewer agreement, 3) comparing that agreement to agreement before implementation of structured peer review, and 4) further enhancing the piloted set of structured peer review questions. Methods: Structured peer review consisting of nine questions was piloted in August 2022 in 220 Elsevier journals. We randomly selected 10% of these journals across all fields and IF quartiles and included manuscripts that received two review reports in the first 2 months of the pilot, leaving us with 107 manuscripts belonging to 23 journals. Eight questions had open-ended fields, while the ninth question (on language editing) had only a yes/no option. The reviews could also leave Comments-to-Author and Comments-to-Editor. Answers were independently analysed by two raters, using qualitative methods. Results: Almost all the reviewers (n = 196, 92%) provided answers to all questions even though these questions were not mandatory in the system. The longest answer (Md 27 words, IQR 11 to 68) was for reporting methods with sufficient details for replicability or reproducibility. The reviewers had the highest (partial) agreement (of 72%) for assessing the flow and structure of the manuscript, and the lowest (of 53%) for assessing whether interpretation of the results was supported by data, and for assessing whether the statistical analyses were appropriate and reported in sufficient detail (52%). Two thirds of the reviewers (n = 145, 68%) filled out the Comments-to-Author section, of which 105 (49%) resembled traditional peer review reports. These reports contained a Md of 4 (IQR 3 to 5) topics covered by the structured questions. Absolute agreement regarding final recommendations (exact match of recommendation choice) was 41%, which was higher than what those journals had in the period from 2019 to 2021 (31% agreement, P = 0.0275). Conclusions: Our preliminary results indicate that reviewers successfully adapted to the new review format, and that they covered more topics than in their traditional reports. Individual question analysis indicated the greatest disagreement regarding the interpretation of the results and the conducting and the reporting of statistical analyses. While structured peer review did lead to improvement in reviewer final recommendation agreements, this was not a randomized trial, and further studies should be performed to corroborate this. Further research is also needed to determine whether structured peer review leads to greater knowledge transfer or better improvement of manuscripts.
