Dr. Yoshitaka Fujii, formerly an anesthesiologist at Toho University's medical school, has a record no published researcher can match. He is 209 and 3. The problem is the 3 are papers of his that are known not to be fraudulent between 1993 and 2011.
172 are clearly based on fabricated data, according to Retraction Watch. Naturally, Fujii claimed the studies were all randomized, double-blind, controlled trials and done at multiple institutions to throw off fact checkers, the way these guys always do. Some even had forged signatures of collaborators.
Apparently the whole field is a little sketchy. John Timmer at Ars Technica notes that 13% of papers retracted over the last four decades have been in anesthesiology.
37 of his papers were not included in the analysis so there is a chance he could extend his world record even more.
