Abstract

Background: This systematic review aimed to investigate the relationship between retraction status and the methodology quality in the retracted non-Cochrane systematic review. Method: PubMed, Web of Science, and Scopus databases were searched with keywords including systematic review, meta-analysis, and retraction or retracted as a type of publication until September 2023. There were no time or language restrictions. Non-Cochrane medical systematic review studies that were retracted were included in the present study. The data related to the retraction status of the articles were extracted from the retraction notice and Retraction Watch, and the quality of the methodology was evaluated with the AMSTAR-2 checklist by two independent researchers. Data were analyzed in the Excel 2019 and SPSS 21 software. Result: Of the 282 systematic reviews, the corresponding authors of 208 (73.75%) articles were from China. The average interval between publish and retraction of the article was about 23 months and about half of the non-Cochrane systematic reviews were retracted in the last 4 years. The most common reasons for retractions were fake peer reviews and unreliable data, respectively. Editors and publishers were the most retractors or requestors for retractions. More than 86% of the retracted non-Cochrane SRs were published in journals with an impact factor above two and had a critically low quality. Items 7, 9, and 13 among the critical items of the AMSTAR-2 checklist received the lowest scores. Discussion and conclusion: There was a significant relationship between the reasons of retraction and the quality of the methodology (P-value < 0.05). Plagiarism software and using the Cope guidelines may decrease the time of retraction. In some countries, strict rules for promoting researchers increase the risk of misconduct. To avoid scientific errors and improve the quality of systematic reviews/meta-analyses (SRs/MAs), it is better to create protocol registration and retraction guidelines in each journal for SRs/MAs. © 2024, The Author(s).
