All authors must disclose any and all conflicts of interest, they may have with publication of the manuscript or an institution or product that is mentioned in the manuscript and/or is important to the outcome of the study presented. Authors should also disclose conflicts of interest with products that compete with those mentioned in their manuscript. A conflict of interest may exist when an author (or the author’s institution or employer) has financial or personal relationships or affiliations that could influence (or bias) the author’s decisions, work, or manuscript.

CMJ should consider retracting a publication if:

• Editors 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.
