Tranexamic acid did not reduce the rate of death from bleeding within five days, which was four per cent in both groups, in this study that included 12,009 patients. The rate of arterial thromboembolic events was similar in both groups, but venous thromboembolic events were more common with tranexamic acid: 0.8 versus 0.4 per cent, relative risk 1.15 to 2.98.
