	AUC(95%CI)	Cut-off(95%CI)	Specificity (%)	Sensitivity (%)	Accuracy (%)	P
level 0	0.96(0.93–0.99)	0.54(0.53–0.57)	95.50	93.60	95.00	< 0.0001
level 1	0.86(0.78–0.93)	0.59(0.58–0.63)	87.00	81.30	83.30	< 0.0001
level 2	0.81(0.71–0.91)	0.73(0.68–0.74)	65.70	89.10	79.01	0.0311
level 3	0.87(0.79–0.95)	0.86(0.82–0.88)	76.50	88.60	81.40	0.0092

AUC, Area Under the Curve; CI, confidence interval; level 0 represents normal subjects vs. all hepatic steatosis patients. level 1 represents normal individuals vs. mild hepatic steatosis patients. level 2 represents patients with mild hepatic steatosis vs. patients with moderate hepatic steatosis. level 3 represents patients with moderate hepatic steatosis vs. patients with severe hepatic steatosis
