A Norwegian doctor, Jon Sudbo, who published an article in the Lancet last year suggesting that aspirin could reduce the risk of oral cancer, has been accused of making up the data in his study. Specifically, he invented almost all of the 900 patients in the study (or at least half of them, by other accounts). The director of the hospital where he worked said: "he faked everything: names, diagnosis, gender, weight, age, drug use." Richard Horton, editor of the Lancet, said: "What I've been told is that he sat in front of his computer and made the whole dataset up and convinced his co-authors it was genuine... It's completely inexplicable." I guess that's one way to avoid having to get consent forms signed.

Other journals, including the New England Journal of Medicine, are now finding evidence of fraud in articles they published by Sudbo.
