JMMC is committed to the integrity of the published academic record. Whenever a significant inaccuracy, misleading statement, or distorted report is identified in a published article, it will be corrected promptly and with due prominence. Where an appropriate investigation confirms an item to be fraudulent, it will be retracted. Retractions are made clearly identifiable to both readers and indexing systems.

 

Corrections
Errors in published papers may be addressed through a corrigendum or erratum, where the Editor-in-Chief considers it appropriate to inform readers of a previous error and correct it. The corrigendum or erratum appears as a new article in the journal and cites the original published article.

 

Retractions
Retractions are considered and published where an article contains severe errors that invalidate its conclusions, or where there is evidence of publication malpractice such as plagiarism, duplicate publication, or unethical research.

In line with COPE's retraction guidelines, JMMC follows this procedure when a retraction is confirmed:

1. A retraction note titled "Retraction: [article title]," signed by the authors and/or the editor, is published in a subsequent issue of the journal and listed in its contents.
2. A link is made from the retraction note to the original article in the electronic version.
3. The online article is preceded by a screen containing the retraction note; readers must pass through this screen before proceeding to the article itself.
4. The original article is retained unchanged, except for a watermark on the PDF indicating on every page that it has been retracted.

 

Editorial Expressions of Concern
Where substantial doubt arises about the honesty or integrity of a submitted or published article, journal editors may issue an expression of concern. This is only done where an investigation into the article has proven inconclusive but strong indicators remain that the concerns are valid, or in rare cases where an investigation is underway but a judgment will not be available for a considerable time. The expression of concern is linked back to the article it relates to.
