Are you aware of your citations? A cross-sectional survey on improper citations of retracted articles in assisted reproduction

Are authors aware when they have cited a retracted paper in their manuscripts in the medically assisted reproduction (MAR) field? A cross-sectional study based on an online survey was conducted to acquire information on the citation pattern from corresponding authors who had cited a retracted article. A dataset of retracted articles in the MAR field was collected from PubMed and Retraction Watch. A complete list of published articles that cited each retracted article was retrieved. The survey was distributed via e-mail to corresponding authors who had cited a retracted paper in their study. The survey revealed a significant lack of awareness among authors, with 78.7% unaware that they had cited retracted articles. This lack of awareness was attributed to insufficient notification mechanisms within research databases and journals, alongside a reliance on previously stored copies of manuscripts. A notable finding was that reference checks were typically performed by a single author, with no instances of retraction concerns raised during the peer-review process. Only a small fraction (17.8%) of respondents reported verifying retraction notices on both journal websites and scientific databases. Correcting publications that contain references which are subsequently retracted is significant for systematic reviews, meta-analyses and guidelines. Citations of retracted articles perpetuate erroneous scientific data, but assessing the accuracy of citations requires considerable effort. Proper notification of retraction status and cross-checking of citations can help to prevent errors.
