*The endpoint of target vessel failure is a composite of cardiac mortality, target vessel-related myocardial infarction, and clinically indicated target vessel revascularization

^†Target lesion failure is a composite of cardiac mortality, target vessel-related myocardial infarction, and clinically indicated target lesion revascularization

^‡Major adverse cardiac events is a composite of all-cause mortality, any myocardial infarction, emergent coronary artery bypass surgery, and clinically indicated target lesion revascularization
