Simultaneous Publication Raises Concerns of Duplicate Data in Papers from Journals
About a month after the publication of Paper X in Journal A, concerns were raised by readers who found similarities between Paper X and a recently published Paper Y in Journal B. While the two papers superficially appeared different, they shared highly similar results and conclusions. The co-corresponding authors for both papers were significantly overlapping, and Paper X's authors were aware of Paper Y's acceptance by Journal B when submitting revisions.
Upon contacting the authors, they highlighted differences between the papers but insisted that the results were obtained separately. Reviewers, editorial board members, and concerned readers found the papers highly similar. Journal A reached out to Journal B, where the Editor was satisfied with the authors' explanation.
COPE advised Journal A to publish a notice of concern and consider a notice of duplication if it became clear that the data were the same. COPE emphasized against imposing sanctions or banning authors. The case was under investigation by the authors' institution, and the communication from the institution to the authors confirmed adherence to proper author/researcher conduct.
While the investigation by the authors' institution satisfied Journal A, the publication of a notice of concern serves as a transparent acknowledgment of the issue and a commitment to addressing concerns raised by readers. The case underscores the importance of maintaining the integrity of the publication process and ensuring transparency when potential issues arise.
