How many retractions have authors with the most retractions (ie, superretractors) and top-cited authors with multiple retractions contributed to the retracted randomized clinical trial literature?In this cohort study of 367 authors and 1330 retracted randomized clinical trials, 6 superretractors, from anesthesiology as well as endocrinology and metabolism, coauthored one-fifth of all retracted trials, while 18 top-cited scientists with more than 10 retractions coauthored one-quarter of them. Articles coauthored by superretractors or by top-cited scientists with multiple retractions were published and retracted earlier, took longer to retract, and accumulated more citations.This study found that retracted randomized clinical trials were disproportionately associated with a small number of influential authors, often coauthors, and concentrated across few subfields of medicine.
