An article was published in July. In October, a corrigendum was published to correct large sections of unattributed text. Two weeks later the journal and publisher received a complaint from a reader who accused the author of the published article of using text from an unpublished collaborative manuscript on which the published author was participating. This participation on the collaborative work was initiated and ongoing during the time that the manuscript was being prepared for publication at the journal. The unpublished collaborative work has not yet been published.
The reader requested retraction of the published article, with the possibility of a republication only when all collaborators of the unpublished work were in agreement with the article content.
The publisher and journal initiated the procedure outlined in the COPE flowchart 'Suspected plagiarism in a published manuscript'. The editor-in-chief has requested feedback from the published author on the reason for the large overlap in text.
Question(s) for the COPE Forum
• Should the publisher and journal publish an 'expression of concern' while continuing with the investigation?
• Is this the correct approach in this situation?
The editor told the Forum that she had checked the articles and the degree of overlap of text was nearly 20%. The Forum warned that percentages can be misleading, and the editor needs to look carefully at where the overlap occurred (in the introduction and methods may be fine, but it can be more problematic in the results or conclusion sections).
The institution(s) may need to be involved in this case.
The Forum would advise against an expression of concern on the article as these are generally used for ongoing unresolved cases. In this case, there is nothing proven or finalised —it may ‘end’ in a correction or a retraction. Hence it may be premature to publish an expression of concern and the editor should wait for a response from the authors. There is also the issue of the negative connotations of an expression of concern and/or stigma for the author, which may be unwarranted
A suggestion was for a less permanent ‘Editor’s note’ on the article for now, written in neutral terms.
As there seems to be clear grounds for self-plagiarism, the Forum would suggest consulting the COPE/BioMed Central guidelines on text recycling.
The journal’s review of the guidelines on text recycling led to the conclusion that the scientific content was not disputed, and in fact the article adds to the body of knowledge. Also, the text recycling was not in the discussion or conclusions but rather in the methodology. The journal decided not to publish an expression of concern or retract the publication. The editor considers the case closed.
