Figure 1 Receiver operating characteristic (ROC) curve for EBCT coronary scanning. The area under the curve is 0.75 ± 0.05, which represents the ability of EBCT to detect patients with obstructive CAD. CAD = coronary artery disease; EBCT = electron beam computed tomography.

Figure 2 Receiver operating characteristic (ROC) curve for EBCT coronary scanning combined with treadmill-ECG. The area under the curve is 0.79 ± 0.05, which represents the ability of the combination of EBCT and treadmill-ECG to detect patients with obstructive CAD. CAD = coronary artery disease; EBCT = electron beam computed tomography; treadmill-ECG = exercise electrocardiogram treadmill stress testing.
