RETRACTION NOTE

Retraction note to: Iwamoto J, Sato Y, Takeda T, Matsumoto H. Strategy for prevention of hip fractures in patients with Parkinson’s disease. World J Orthop 2012; 3(9):137-141 PMID: 23173109 DOI: 10.5312/wjo.v3. i9.137. The online version of the original article can be found at https://www.wjgnet.com/2218-5836/full/v3/i9/137.htm

This meta-analysis article[1] has been retracted at the request of the Co-Editors-in-Chief, as a substantial portion of the primary studies on which the review was based [References 12, 14, 15] have subsequently been retracted.

The Editors-in-Chief recently received communications indicating that 3 of the 5 articles on which the study was based upon were retracted, raising concerns about the integrity of the meta-analysis and its findings. The Editorial Office has conducted an investigation and has contacted the authors concerning the allegation. The authors declare that at the time the article was written, none-except for Dr. Yoshihiro Sato were aware of the fact that the studies subject to the analysis had been fraudulently conducted. The authors have agreed to retract the article from the Journal.
