The ISIS-2 trial recruited 17,187 patients from 417 hospitals. The authors concluded that there were benefits both from streptokinase and from aspirin. This paper contained a complex table reporting subgroup analyses, and rather intriguingly, the first analysis was by astrological birth sign. The results suggested that for people born under the star signs Gemini and Libra, aspirin was no better than placebo; for others, aspirin had a strongly beneficial effect. Why, one might wonder, did a highly respected journal publish such arrant nonsense? …
