Antiplatelet drug appears effective for women

There was no significant difference in severe bleeding between the treatment arms for men or women, but women had a significantly higher risk of moderate bleeding if they received cangrelor.

For women, the rate of severe bleeding was 0.3% in the cangrelor arm and 0.2% in the clopidogrel arm (aOR=2.37, P=0.30). For men, the rates were 0.1% in both arms (aOR=2.04, P=0.41, P interaction=0.88 ).

For women, the rate of moderate bleeding was 0.9% in the cangrelor arm and 0.3% in the clopidogrel arm (aOR=3.63, P=0.02). For men, the rates were 0.2% in both arms (aOR=0.81, P=0.68, P interaction=0.04).
