A bone researcher based in Japan with 10 retractions under his belt has retracted two more papers for similar reasons — problems with the underlying data, and including co-authors who didn’t participate in the project.
In both notices, Yoshihiro Sato is pegged as responsible for the content of the papers. The newly retracted research covers a long timespan — one paper was published in 2000, the other in 2013.
The latest retraction stemmed from a re-analysis of the paper by the Canadian Multicentre Osteoporosis Study Group, of which the paper was a part; all authors but Jamal have requested the retraction. In the notice, the authors say that they believe no patients were harmed as a result of the “possibly invalid conclusions” in the paper, which showed patients with kidney problems were at higher risk of bone loss. A researcher told us a third paper by Jamal is also due to be retracted soon.
Once again, this list focuses on duplications — but unlike other duplications, these authors were not at fault. Rather, these retractions occurred because the publishers mistakenly published the same paper twice — the result of a transfer between publishers, for instance, or accidentally publishing the unedited version of the paper. We’re forced to wonder, as we have before, whether saddling researchers’ CVs with a retraction is really the most fair way to handle these cases.
Sato, who is the first and corresponding author of all ten retractions (including the letter), accepted full responsibility of the newly retracted publications, noting that none of the co-authors took part in any misconduct.
A rheumatology journal has retracted a paper about treating knee pain after an institutional investigation found a mistake in the statistical process.
Over several months, the authors proposed a series of corrections to the 2014 study. However, the journal Annals of the Rheumatic Diseases (ARD) decided that there were “unresolved concerns” about the reliability of the data, and decided to retract the paper entirely, despite the authors’ objections.
A team of researchers from Japan has earned a fifth retraction, after co-authors told the journal that they did not participate in much of the paper.
Yoshihiro Sato, listed at Mitate Hospital, is the only author of the paper who was not “honorary,” the managing editor of the journal confirmed. He and the same co-authors recently lost three other papers about preventing hip fractures for “concerns regarding data integrity” and authorship issues — one of those papers, published in JAMA, specified that Sato was responsible for the data. All four authors were also included in a retraction last year of a paper with “concerns about the underlying data;” there, too, Sato said his co-authors were named “for honorary reasons.”
JAMA and another journal in its network have retracted three 2005 papers about preventing hip fractures, after an admission of scientific misconduct.
All papers are being retracted over concerns about data integrity, and “inappropriate assignment of authorship.” Four of the authors — all based in Japan — have co-authored all of the three newly retracted papers, and also share authorship of a previous retraction from 2015.
