Table 2. ROC curve analyses showing value of baPWV predicting obstructive CAD.

SSS value	Area under curve	95% confidence interval	p
4–8 (mild ischemia)	0.714	0.60–0.82	0.001
9–13 (moderate ischemia)	0.510	0.33–0.68	0.927
≥ 14 (severe ischemia)	0.302	0–0.61	0.142

ROC, receiver operating characteristic; baPWV, brachial-ankle pulse wave velocity; CAD, coronary artery disease; SSS, summed stress score.
