An analysis of retracted COVID-19 articles published by one medical publisher with multiple journals

The retraction of medical articles periodically occurs in most medical journals and can involve multiple article types. These retractions are beneficial if they remove flawed or fraudulent information from the medical literature. However, retractions may also decrease confidence in the medical literature and require significant amounts of time by editors.

One publisher (Hindawi) announced that it will retract over 1200 articles. Given this, the PubMed database was searched to identify retracted publications on or related to COVID-19, and articles retracted by journals sponsored by the publisher Hindawi were then identified.

These journals retracted 25 articles and, in most cases, did not provide an exact explanation about the particular problem(s) resulting in the retraction. The time to retraction was 468.7 ± 109.8 days (median =  446 days). These articles had 9.3 ± 9.9 citations.

Analysis of the titles and abstracts of the articles suggests that their removal from the medical literature would have limited effects on the near-term management decisions during the COVID-19 pandemic. Nevertheless, retraction of medical articles creates uncertainty in medical care and science and in the public regarding the validity of medical research and related publications and the level of professionalism of the individuals submitting these articles.
