Assessing and Raising Concerns About Duplicate Publication, Authorship Transgressions and Data Errors in a Body of...

Authorship transgressions, duplicate data reporting and reporting/data errors compromise the integrity of biomedical publications. Using a standardized template, we raised concerns with journals about each of these characteristics in 33 pairs of publications originating from 15 preclinical (animal) trials reported by a group of researchers. The outcomes of interest were journal responses, including time to acknowledgement of concerns, time to decision, content of decision letter, and disposition of publications at 1 year. Authorship transgressions affected 27/36 (75%) publications. The median proportion of duplicate data within pairs of publications was 45% (interquartile range 29-57). Data/reporting discrepancies [median 3 (1-5)] were present in 28/33 (85%) pairs. Journals acknowledged receipt of concerns for 53% and 94% of publications by 1 month and 9 months, respectively. After 1 year, journals had communicated decisions for 16/36 (44%) publications. None of the decision letters specifically addressed each of the concerns raised. Decisions were no action, correction and retraction for 9, 3 and 4 publications, respectively: the amounts of duplicate data reporting and data/reporting discrepancies were similar irrespective of journal decision. Authorship transgressions affected 6/9 (67%) publications for which no action was decided. Journal responses to concerns about duplicate publication, authorship transgressions, and data/reporting discrepancies were slow, opaque and inconsistent.
