Table 3. ROC Curve Analysis of Variables that were Significant at Univariate Analysis.

	AUC	95% Confidence Interval	Best Cutoff	P
TAG	0.778	0.702–0.843	-18.8 HU/10 mm	< 0.001
MB length	0.663	0.579–0.739	24.6 mm	< 0.001
MB depth	0.620	0.535–0.699	1.5 mm	0.012

AUC = area under curve, HU = Hounsfield units, MB = myocardial bridge, ROC = receiver operating characteristic, TAG = transluminal attenuation gradient
