Fig. 4. ROC curves for predicting high-risk CAD patients. (A) A plot showing the predictive power of traditional clinical risk factors alone (red), mean maximal CIMT measured from left/right CCA and bulb (max-CIMT), and carotid plaques ≥2, in addition to clinical risk factors, using the WHUS and the standard device, shown in blue and green, respectively. (B) The cutoff max-CIMT values and in predicting high-risk CAD patients using the standard (1.05 mm) and WHUS (1.10 mm) device. ROC, receiver operating characteristic; AUC, area under the curve; CAD, coronary artery disease; WHUS, wireless hand-held ultrasound.
