Receive Operating Characteristic Curves: Symptomatic and Asymptomatic Subgroups. Receiver operating characteristic (ROC) curves 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 A. subgroup of symptomatic patients referred for testing and B. subgroup of asymptomatic patients referred for coronary artery disease screening. Only data from those patients who were assessable by all three strategies (n = 74 for the symptomatic subgroup and n = 77 for the asymptomatic subgroup) were included in the ROC analyses. CAC = coronary artery calcification. CI = confidence interval
