a
Composite cardiovascular events were defined as the first occurrence of unstable angina, myocardial infarction, or revascularization, including percutaneous coronary intervention or coronary artery bypass graft.
b
Composite end point of cerebrovascular disease was defined as the first occurrence of stroke (ischemic or hemorrhagic stroke), cerebral infarction, transient ischemic attack, carotid intervention, or surgery.
c
Composite coronary artery interventions were based on the requirement for coronary stenting, percutaneous coronary intervention, or coronary artery bypass.
