The articles in Table 1 by Dr. Yoshitaka Fujii were retracted last year. At that time, the articles in Table 2 were under review by the University of Tsukuba. The University of Tsukuba completed its review in December, 2012. Based on that review, the articles in Table 2 are hereby retracted.

Articles hereby retracted, based on the recently completed review by the University of Tsukuba

The retraction of Dr. Fujii’s research is based on overwhelming statistical evidence of fabrication.1,2 Dr Fujii’s institutions were asked to attest to the integrity of published investigations conducted under their auspices, as set out in the Joint Editors-in-Chief Request for Determination of April 9, 2012.1a The response from each institution, as well as an analysis of Dr. Fujii’s published research by the Japanese Society of Anesthesiologists, is available online.2b

The University of Tsukuba affirmed the validity an article by Dr. Uemura3 for which Dr. Fujii was a coauthor. This article remains part of the unimpeached medical literature. It is the only surviving manuscript by Dr. Yoshitaka Fujii in Anesthesia & Analgesia.
