Abbreviations: CAG, coronary angiography; MPS, myocardial perfusion scintigraphy
*MPS was used for endpoint grading when CAG was not available
†primary endpoint, documented significant coronary artery disease
‡secondary endpoint, Class I or IIa indication for a revascularization procedure in asymptomatic patients
