Reasons for retraction of clinical research articles in PubMed indexed medical journals from 2012 to 2022.

Abstract

Background: Misconduct in the publication of research articles is a serious concern for the scientific community. This study was conducted with the objective to assess various reasons for retraction of clinical research articles published in PubMed indexed journals from all over the world since 2012 to 2022.

Methods: A search was performed on the PubMed database for retracted research articles using filters for "retracted publication". A total of 314 eligible research articles were assessed for studying basic details. The study outcome measures were to evaluate the reasons for the retraction and authors' and journal editors' responses to retractions.

Results: Of the original research articles retracted, 150/242 (61.98%) were clinical trial publications. Of the total 314 retracted research articles, the most retractions were in 2014 (47, 14.96%) and 2013 (40, 12.73%) while the fewest retractions were in 2012 (3, 0.95%) and 2022 (9, 2.86%). The most common reasons for retraction were data errors or data analysis errors (120/314, 38.21%) followed by plagiarism (37/314, 11.8%), duplicate publication (35/314, 11.1%), ethical concerns (23/314, 7.3%) and methodological flaws (22/314, 7%). These concerns were raised mainly by the editor or editor-in-chief (228/314, 72.61%), followed by authors (29/314, 9.23%). Out of 228 editorial concerns on publications, authors of only 91/228 (39.91%) agreed and 17/228 (7.45%) completely disagreed with the editorial decision.

Conclusion: Authors need to be more careful about data analysis errors, fabricated or falsified data, and plagiarism while submitting their research papers. On the part of editors, detecting misconduct at the submission and peer review stages will help lower the retraction rate and avoid citation of such articles by other authors.
