Assessing time-dependence of aspirin treatment for males and females on risk of clinically significant bleeding. The overall estimated HR(t) for treatment effect is the solid green line with the shaded green area indicating the 95% CI width. The HR(t) for treatment effect estimated from females only is indicated by a purple dashed line and the HR(t) for treatment effect estimated from males only indicated by the blue dashed line
