  1. BMI, body mass index; WC, waist circumference; SBP, systolic blood pressure; DBP, diastolic blood pressure; TP, total protein; ALT, alanine aminotransferase; AST, aspartate transaminase; Cre, Creatinine; BUN, blood urea nitrogen; eGFR, estimated glomerular filtration rate; TC, total cholesterol; LDL-C, low-density lipoprotein cholesterol; TG, triglycerides; HDL-C, high-density lipoprotein cholesterol; FBG, fasting blood glucose; VFA, visceral fat area; SFA, subcutaneous fat area; TFA, total fat area; MetS, metabolic syndrome. OR, odds ratio; CI, confidence interval. Except for ALT, which are expressed as medians (upper and lower quartiles), all other continuous variables are expressed as mean ± standard deviation, and categorical variables are expressed as counts (%). For categorical variables, reference groups are as indicated. For continuous variables, OR represent the risk per unit increase
