Correction of the Scientific Production: Publisher Performance Evaluation Using a Dataset of 4844 PubMed Retractions

Background. Retraction of problematic scientific articles after publication is one of the mechanisms for correcting the literature available to publishers. The market volume and the busi-ness model justify publishers’ ethical involvement in the post-publication quality control (PPQC) of human-health-related articles. The limited information about this subject led us to analyze Pub-Med-retracted articles and the main retraction reasons grouped by publisher. We propose a score to appraise publisher’s PPQC results. The dataset used for this article consists of 4844 Pub-Med-retracted papers published between 1.01.2009 and 31.12.2020. Methods. An SDTP score was constructed from the dataset. The calculation formula includes several parameters: speed (article exposure time (ET)), detection rate (percentage of articles whose retraction is initiated by the edi-tor/publisher/institution without the authors’ participation), transparency (percentage of retracted articles available online and the clarity of the retraction notes), and precision (mention of authors’ responsibility and percentage of retractions for reasons other than editorial errors). Results. The 4844 retracted articles were published in 1767 journals by 366 publishers, the average number of retracted articles/journal being 2.74. Forty-five publishers have more than 10 retracted articles, holding 88% of all papers and 79% of journals. Combining our data with data from another study shows that less than 7% of PubMed dataset journals retracted at least one article. Only 10.5% of the retraction notes included the individual responsibility of the authors. Nine of the top 11 publishers had the largest number of retracted articles in 2020. Retraction-reason analysis shows considerable differences between publishers concerning the articles’ ET: median values between 9 and 43 months (mistakes), 9 and 73 months (images), and 10 and 42 months (plagiarism and overlap). The SDTP score shows, from 2018 to 2020, an improvement in PPQC of four publishers in the top 11 and a decrease in the gap between 1st and 11th place. The group of the other 355 publishers also has a positive evolution of the SDTP score. Conclusions. Publishers have to get involved actively and measurably in the post-publication evaluation of scientific products. The introduction of reporting standards for retraction notes and replicable indicators for quantifying publishing QC can help increase the overall quality of scientific literature.
