Summary of Findings An author of a Cochrane review of drugs for preventing postoperative nausea and vomiting (2006) that was later found to include fabricated trials, raises issues regarding inclusion and reliance of multiple secondary research syntheses that include fabricated, retracted trials discusses two examples in anaesthesiology. One example is Dr Yoshitaka Fujii, who has had 183 (of 193) studies retracted due to statistically unlikely data distributions. Another example is (Professor Joachim Boldt), who had 88 retractions, based largely on failures to gain appropriate ethical approval. The author flags that both of these individuals' studies, both retracted and active continue to be included in systematic reviews and highlight the need for Cochrane to develop clear policy for dealing with retracted studies and authors of retracted studies.
