Receiver Operating Characteristic Curve: Entire Cohort. Receiver operating characteristic (ROC) curve with area under the curve (AUC) values for the combined coronary artery disease assessment strategy (functional testing, coronary artery calcification assessment, and guideline-recommend statin therapy discussion with the number of combined abnormal results (zero, one, two, or three) as the cut points) in the entire cohort. Only data from those patients who were assessable by all three strategies (n = 151) were included in the ROC analyses. CAC = coronary artery calcification. CI = confidence interval
