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