[Comment] Transparency of retracting and replacing articles

Journal editors are responsible for the integrity of the published record and must correct it when necessary. They are getting better at this job, as evidenced by journal retraction policies1 and numbers of article retractions.2 Most retractions are due to misconduct, but about 20% are retracted because of an unintentional error or methodological flaw.2 To credit the correction of an honest error and avoid stigmatisation of authors, journals have begun a practice of retraction with republication of a corrected article.
