All clinical events are described as n (annual event rate). Composite events taking account of the first occurrence of cardiac death or non-fatal MI.
MI, Myocardial infarction; UAP, unstable angina pectoris.
#One myocardial infarction was procedure related this MI was not considered as a cardiac event for the current analyses.
