As a pulmonary doc, big fan of Sir Richard Peto’s work on tobacco use-lung cancer, but I was unaware of his humorous forced subgroup analysis of the ISIS-2 trial:
‘To demonstrate the unreliability of subgroup analyses, these findings were subdivided into 12 subgroups according to the patients’ medieval astrological birth signs; the results in each were examined to find which of the 12 appeared least promising, and when just those with apparently unpromising results were collected together, it was ‘discovered’ that aspirin appeared totally ineffective for patients born under Libra or Gemini’
