Editor-in-Chief considers retracting a publication if the following criteria
They have clear evidence that the findings are unreliable, either because of a major error (e.g., miscalculation or experimental error), or because of fabrication (e.g., of data) or falsification (e.g., image manipulation). It constitutes plagiarism
The findings have previously been published elsewhere without proper attribution to previous sources or disclosure to the editor, permission to republish, or justification (i.e., cases of redundant publication). It contains material or data without authorisation for use
Copyright has been infringed, or there is some other legal severe issue (e.g. libel, privacy). It reports unethical research. It has been published solely based on a compromised or manipulated peer review process
The author(s) failed to disclose a major conflict of interest that, in the editor's view, would have unduly affected interpretations of the work or recommendations by editors and peer reviewers.
Notices of retraction should
Be linked to the retracted article wherever possible (i.e., in all online versions)
Clearly identify the retracted article (e.g., by including the title and authors in the retraction heading or citing the retracted article)
Be clearly identified as a retraction (i.e., distinct from other types of correction or comment)
Be published promptly to minimise harmful effects
Be freely available to all readers (i.e., not behind access barriers or available only to subscribers)
State who is retracting the article
State the reason(s) for retraction
Be objective, factual and avoid inflammatory language
Retractions are not usually appropriate if
The authorship is disputed, but there is no reason to doubt the validity of the findings
The main findings of the work are still reliable, and correction could sufficiently address errors or concerns
An editor has inconclusive evidence to support retraction or is awaiting additional information such as from an institutional investigation
Author conflicts of interest have been reported to the journal after publication, but in the editor's view, these are not likely to have influenced interpretations or recommendations or the conclusions of the article.
