Design outcomes

Primary

MeasureTime frame
1.Composite endpoint of first stroke, systemic arterial embolism, myocardial infarction or cardiovascular death 2.Composite endpoint of first unplanned cardiovascular hospitalization or death from any causeTimepoint: 1.The Common Study End Date will be anticipated based on the projected blind number of events to reach 844 coprimary events not refuted by adjudication (stroke, systemic arterial embolism, myocardial infarction or cardiovascular death) but cannot be less than 3 months after the last patient randomized
