As Retraction Watch readers may know, as part of keeping our database of retractions up to date, we’ve been publishing a running list of COVID-19 papers that have been retracted. That list has been steadily growing since the end of April, but yesterday the number jumped from 45 to 72, so we thought we’d walk through where the additional retractions came from.
While the number may seem large, it’s about 0.4% of the total number of papers about COVID19 published. Nevertheless, in the context of the dire need and public exposure, even this tiny fraction is unfortunate.
We’ve divided the list of retractions into three groups: Retracted, Retracted due to journal error, and Retracted and reinstated. Those in the last category have simply been replaced without notice — also often by Elsevier. And we have removed the “temporarily retracted” category, but noted in the Retracted list if a paper is — perhaps for months — marked that way. (We also include a list of expressions of concern that doesn’t count toward the 72.) For reasons we explain on the page, we count withdrawals as retractions.
