Recurrent spontaneous abortion and polycystic ovarian disease: comparison of two regimens to induce ovulation

Following an investigation carried out by St George's Hospital Medical School, London, of 23 scientific papers written by Mr J M Pearce and various co-authors between January 1989 and December 1994 the dean of the school has written to the BMJ to say that there are reasons to cast doubt on the veracity of the following paper: Johnson P, Pearce J. Recurrent spontaneous abortion and polycystic ovarian disease: comparison of two regimens to induce ovulation. BMJ 1990;300:154-6.

The dean's report states that the study had apparently taken place before Dr Johnson joined the department in August 1988 and that she was handed a sheet of handwritten summary data by Mr Pearce which she then shaped into a paper on his instructions. “No identifiable patient details have been traced. Neither the names of the patients nor their hospital numbers appear on the summary data sheets to provide direct corroboration that the work took place.” The medical school's investigation followed allegations that he had fraudulently claimed to have performed an operation (17 June, p 1554). We therefore think this is sufficient evidence for us to retract the article.
