Odd ratio (OR) calculated by univariate logistic regression analysis. A indicates A blood group; B indicates B blood group; O indicates O blood group; AB indicate AB blood group; TC: total cholesterol; TG: triglycerides; HDL-c: high density lipoprotein cholesterol; LDL-c: low density lipoprotein cholesterol; WC: waist circumference.
