According to the results reported on ClinicalTrials.gov, this trial (known as ARISTOTLE) enrolled 18,201 people with a heart rhythm problem called atrial fibrillation who were at risk of stroke. Participants were randomly assigned to take either apixaban (9,120 people) or warfarin (9,081 people). The trial was measuring how often people experienced a stroke or a blockage of blood flow to a part of the body (called systemic embolism), as well as serious bleeding episodes and deaths from any cause. The reported data shows that for the primary outcome — stroke or systemic embolism — 212 participants in the apixaban group and 265 in the warfarin group had at least one such event during the study period. Broken down further, the reported figures include 159 apixaban participants and 173 warfarin participants with an ischaemic or unspecified stroke, 38 versus 76 with a haemorrhagic (bleeding into the brain) stroke, and 15 versus 16 with systemic embolism. Expressed as a rate per 100 person-years (a way of accounting for different lengths of follow-up), this was 1.27 for apixaban and 1.60 for warfarin. For serious bleeding, 327 people in the apixaban group and 462 in the warfarin group experienced a major bleed, corresponding to rates of 2.13 and 3.09 per 100 person-years respectively. For deaths from any cause, 603 people in the apixaban group and 669 in the warfarin group died during the intended treatment period, at rates of 3.52 and 3.94 per 100 person-years.
