Figure 3 Comparison of Outcomes Among Patient Groups

(Left) Kaplan-Meier survival curves for freedom from cardiac death or myocardial infarction in the propensity-matched coronary artery calcium (CAC) and myocardial perfusion scintigraphy (MPS) cohorts who had no ischemia during stress MPS testing. (Right) Kaplan-Meier survival curves for the propensity-matched MPS patients with coronary artery disease likelihood (LL) values <15%, 15% to 85%, and 85% and for the patients with CAC scores 1,000. There were no statistical differences among the subgroups.
