Table 3. AUC Analysis of the Predictive Value of Various Parameters for CAS.

CVD risk estimators	Predictive value of the presence of CAS (≥20%)			Predictive value of significant CAS (≥50%)
	AUC	95% CI	P value	AUC	95% CI	P value
Maximal baPWV	0.672	0.554–0.785	0.010	0.605	0.483–0.728	0.104
UKPDS risk engine	0.777	0.675–0.878	<0.001	0.725	0.616–0.834	0.001
ACC/AHA risk estimator	0.763	0.660–0.866	<0.001	0.674	0.558–0.791	0.007
Framingham risk calculator	0.736	0.629–0.843	<0.001	0.701	0.588–0.814	0.002

P values <0.05 were considered to be indicate significance.

AUC, area under the curve; CAS, coronary artery stenosis; CVD, cardiovascular disease; CI, confidence interval; baPWV, brachial ankle pulse wave velocity; UKPDS, United Kingdom Prospective Diabetes Study; ACC/AHA, American College of Cardiology/American Heart Association.
