We decided to retract the paper entitled ‘Comparison of the Effect of Vitamin K2 and Risedronate on Trabecular Bone in Glucocorticoid-Treated Rats: A Bone Histomorphometry Study’ [Yonsei Med J 2009;50(2):189-194] by Iwamoto J, Matsumoto H, Tadeda T, et al. Based on information that were discovered after publication, we have recently become aware of a number of issues related to data duplication and scientific misconduct.
