Last year, a researcher cast doubt on a bone scientist’s clinical trials, suggesting some of the findings may not be legitimate. So what’s happened since? Since 2015, journals have retracted 14 papers by bone researcher Yoshihiro Sato, based at Mitate Hospital in Japan, for issues ranging from self-plagiarism, to problems with data, to including co-authors without their consent. … Continue reading A shadow was cast on a bone researcher’s work. What are journals doing about his papers?
The troubles continue for a bone researcher, who’s lost multiple papers in recent months due to problems ranging from data issues to including authors without their consent. Now, journals have retracted two more papers by Yoshihiro Sato. And in a sign of the downstream effects that fraud can have, another journal has retracted two meta-analyses by other … Continue reading Fraud by bone researcher takes down two meta-analyses, a clinical trial, and review
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 … Continue reading Two more retractions bring bone researcher’s total to 12
A journal is retracting three papers and a letter from a bone researcher who admitted to scientific misconduct, noting that all co-authors were included only for honorary reasons. We’ve previously reported on six retractions of papers co-authored by Yoshihiro Sato, who is based at Mitate Hospital in Japan, including one in JAMA. Retractions stemmed from the … Continue reading Bone researcher up to 10 retractions
A bone researcher in Japan has logged his sixth retraction, after acknowledging he duplicated substantial portions of a 2011 paper and added “honorary” co-authors. The retraction, in Parkinsonism & Related Disorders, follows five others for Yoshihiro Sato, including one from JAMA, some of which were pulled over concerns regarding authorship and data integrity. The latest retraction duplicated … Continue reading Sixth retraction appears for bone researcher due to “extensive self-plagiarism”
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 … Continue reading “All co-authors are honorary:” Team earns fifth retraction
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 … Continue reading JAMA journals pull 3 papers by same authors for misconduct
A paper suggesting that exposure to sunlight might help prevent hip fractures in the elderly has been retracted, due to duplication and “concerns about the underlying data.” An expression of concern that appeared last July flagged the 2005 paper as containing text that matched another paper with the same first author that was published in 2011. According … Continue reading Osteoporosis paper felled by concerns with “scientific integrity”

Six months after we reported that journals had slapped expressions of concern on more than three dozen papers by a group of nutrition researchers in Iran, the retractions have started to trickle in. But clock started nearly two years ago, after data sleuths presented journals with questions about the findings in roughly 170 papers by … Continue reading “Yep, pretty slow”: Nutrition researchers lose six papers
