Early diagnostic value of carotid artery ultrasound parameters combined with epicardial adipose layer thickness in coronary heart disease

Table 4 Receiver operating characteristic curve analysis results

Index	AUC	95%CI	Optimal cutoff value	Sensitivity	Specificity
EAT (mm)	0.872	0.801–0.943	6.35	0.863	0.814
CIMT (mm)	0.826	0.760–0.891	0.95	0.805	0.789
Carotid artery elasticity	0.864	0.803–0.926		0.854	0.802
Combination of the three	0.893	0.839–0.947		0.890	0.837

AUC: Area under the curve; CIMT: Carotid intima-media thickness; EAT: Epicardial fat layer thickness; ROC: Receiver operating characteristic.
