Retracting of articles

Journal editors should consider retracting a publication if:
• They have clear evidence that the findings are unreliable, either as a result of misconduct (e.g. data fabrication) or honest error (e.g. miscalculation or experimental error).
• The findings have previously been published elsewhere without proper crossreferencing, permission or justification (i.e. cases of redundant publication) • it constitutes plagiarism.
• It reports unethical research.
Journal editors should consider issuing an expression of concern if:
• They receive inconclusive evidence of research or publication misconduct by the authors • there is evidence that the findings are unreliable but the authors’ institution will not investigate the case • they believe that an investigation into alleged misconduct related to the publication either has not been, or would not be, fair and impartial or conclusive • an investigation is underway but a judgement will not be available for a considerable time
Journal editors should consider issuing a correction if:
• Asmall portion of an otherwise reliable publication proves to be misleading (especially because of honest error).
• The author / contributor list is incorrect (i.e. a deserving author has been omitted or somebody who does not meet authorship criteria has been included).
Retractions are not usually appropriate if:
• Achange of authorship is required but there is no reason to doubt the validity of the findings.
