The wonderfully informative blog Retraction Watch points out that 3 anesthesiologists – Fujii, Boldt, and an American, Scott Reuben – account for 13% of all papers retracted since 1970.
All but one of Fujii’s co-authors were unaware of his misconduct. In many cases, he included them as authors without telling them and even forged their signatures. However, the latest news comes 12 years after questions were first raised about the validity of his work.
