We have decided to retract the paper entitled “Comparison of the Effects of Alendronate and Alfacalcidol on Hip Bone Mineral Density and Bone Turnover in Japanese Men Having Osteoporosis or Osteopenia with Clinical Risk Factors for Fractures” [Yonsei Med J 2009 Aug;50(4):474-481] by Iwamoto J, Sato Y, Uzawa M, Takeda T, Matsumoto H.
From information obtained after publication, we have recently become aware of a number of issues related to scientific misconduct.
