Model 1: crude model. Model 2: adjusted for age and gender (adjusted only for all subjects). Model 3: further adjusted for SBP, DBP, ALT, SCr, SUA, TG, HDL-C, LDL-C, HbA1c, and HOMA-IR. BMI, body mass index; VFA, visceral fat area; CAP, controlled attenuation parameter; CI, confidence interval; SBP, systolic blood pressure; DBP, diastolic blood pressure; AST, aspartate aminotransferase; SCr, creatinine; SUA, serum uric acid; TG, triglycerides; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; HbA1c, glycosylated hemoglobin A1c; HOMA-IR, homeostasis model assessment-insulin resistance; ALT, alanine aminotransferase.
