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.”
Here’s the retraction notice for “Alendronate and vitamin D2 for prevention of hip fracture in Parkinson’s disease: A randomized controlled trial,” published in Movement Disorders:
The above article, published online on 14 March 2006 in Wiley Online Library (wileyonlinelibrary.com), and in Volume 21, Issue 7, Pages 924–929, has been retracted by agreement between the authors, the Editor-in-Chief, Jose A. Obeso, and Wiley Periodicals, Inc. The retraction has been agreed due to an acknowledgement from the authors that the co-authors did not participate in study design, data collection, data analysis, interpretation of data and drafting the manuscript. Thus all co-authors are honorary.
The 2006 paper has been cited 33 times, according to Thomson Reuters Web of Science.
Julie Nash, the managing editor of the journal, told us:
The International Parkinson and Movement Disorder Society received the request for the retraction of the article directly from Dr. Sato in March 2016. Dr. Sato requested that the paper be retracted on the basis of scientific misconduct. He stated that this was due to a misrepresentation of the work of the co-authors on the paper. After conferring with the publisher, the Movement Disorders editorial staff independently contacted all authors listed on the paper regarding the retraction. Each author confirmed in writing that their authorship was purely honorary and supported the basis of retraction.
Those honorary authors are Jun Iwamoto at the Keio University School of Medicine, and Tomohiro Kanoko and Kei Satoh, both at the Hirosaki University School of Medicine.
