Adjusted model 1: Age, WC, BMI, SBP, DBP, sex, drinking, physical exercise and smoke (baseline indexes); model 2: model 1+AST, ALT, GGT and TB liver markers); model 3: model 2+Cr and UA (kidney markers); model 4: model 3+TC, TG, HDL-C, and LDL-C (lipid markers); model 5: model 4+hsCRP; model 6: model 5+HOMA IR and HbA1c.

ALT, alanine aminotransferase; AST, aspartate aminotransferase; BMI, body mass index; Cr, creatinine; DBP, diastolic blood pressure; GGT, γ-glutamyl transpeptidase; HbA1c, glycated haemoglobin; HDL-C, high-density lipoprotein-cholesterol; HOMA-IR, homoeostasis model assessment-insulin resistance; hsCRP, high-sensitivity C reactive protein; LDL-C, low-density lipoprotein cholesterol; MAFLD, metabolic-associated fatty liver disease; SBP, systolic blood pressure; TB, total bilirubin; TC, total cholesterol; TG, triglycerides; UA, uric acid; WC, waist circumference.
