Annualized event rate (%) = 100 * No. subjects with event / subject-years. Subject-years = Sum (date of last visit - date of first dose + 1) of all subjects / 365.25.

Systemic embolism was an acute vascular occlusion of the extremities or any organ (kidneys, mesenteric arteries, spleen, retina or grafts), and was to be documented by angiography, surgery, scintigraphy, or autopsy.

Pulmonary Embolism was generally documented by one of the following:

1. an intraluminal filling defect in segmental or more proximal branches on spiral CT scan
2. an intraluminal filling defect or an extension of an existing defect or a sudden cutoff of vessels more than 2.5 mm in diameter on the pulmonary angiogram
3. a perfusion defect of at least 75% of a segment with a local normal ventilation result (high-probability) on ventilation/perfusion lung scan (VPLS)
4. inconclusive spiral CT, pulmonary angiography or lung scintigraphy with demonstration of DVT in the lower extremities by compression ultrasound or venography.

a. In subjects not undergoing PCI or CABG a subject should have fulfilled at least 2 of the following: i. Typical prolonged severe chest pain or related symptoms or signs suggestive of MI. ii. Elevation of troponin or CK-MB to more than upper level of normal (ULN) or, if CK-MB was elevated at baseline, re-elevation to more than 50% increase above the previous level. iii. Development of significant Q-waves in at least 2 adjacent ECG leads. b. After percutaneous coronary intervention (within 24h). c. After coronary artery bypass grafting (within 72h). d. Silent myocardial infarction. e. Myocardial infarction could also have been demonstrated at autopsy.

Deep Vein Thrombosis (DVT) was generally documented by one of the following:

1. abnormal compression ultrasound (CUS),
2. an intraluminal filling defect on venography.

Deaths were classified as being vascular (sudden/arrhythmic, pump failure death, or other vascular, including bleeding) or non-vascular, due to other specified causes (e.g., malignancy), or of unknown etiology.

Minor bleeds were clinical bleeds that did not fulfill the criteria for major bleeds. Minor bleeds were classified as associated with study medication discontinuation (temporary or permanent) or not.
