AUC: area under curve; CI: confidence interval; WC: waist circumference; WHtR: waist to height ratio; VAI: visceral adiposity index; LAP: lipid accumulation product; WTI: waist circumference-triglyceride index. *Compared with WC, #Compared with WHtR. The AUCs were similar between VAI, LAP and WTI(P > 0.05).
