bid, twice-daily; CABG, coronary artery bypass graft; CI, confidence interval; CV, cardiovascular; HR, hazard ratio; MI, myocardial infarction; PCI, percutaneous coronary intervention; TIA, transient ischaemic attack.
Event rates are reported as Kaplan–Meier estimates through 24 months and so are not presented as numerical percentages.
n (%): n is the number of subjects with event, % = hazard rate in the corresponding treatment group based on a stratified Cox proportional hazards model.
HR (95% CI): Hazard ratios (95% confidence interval) as compared to placebo arm are based on the stratified (by standard of care with ASA or ASA + thienopyridine) Cox proportional hazards model.
P-values (two-sided) as compared to placebo arm are based on the stratified (by standard of care with ASA or ASA + thienopyridine) log rank test.
n = number of subjects at risk; for efficacy events the mITT (excluding three potentially noncompliant study sites) Analysis Set was used; for safety events the treatment-emergent Safety Analysis Set was used.
Primary efficacy endpoint as adjudicated by the CEC: first occurrence of CV death, MI or stroke.
