To readers of the Journal of Anesthesia: In addition to the articles listed in a retraction note in JAnesth (2013) 27:322, the following articles published by Dr. Yoshitaka Fujii in the Journal of Anesthesia also are hereby retracted as a result of: (1) overwhelming evidence of fabrication related to the fact that the distributions of many variables reported by Dr. Fujii in these studies are exceedingly unlikely [1] and (2) the inability of Dr. Fuji's institution to attest to the integrity of the study and/or the data conducted under its auspices, as set out in the Joint Editors-in-Chief Request for Determination of April 9, 2012. *Fujii Y, Udagawa T, Toyooka H.
