  1. Data are presented as OR, 95% CI, and p value
  2. Model 1: adjusted for nothing
  3. Model 2: adjusted for age, gender, and race
  4. Model 3: adjusted for age, gender, race, education level, PIR, smoke status, alcohol consumption, hypertension, diabetes, moderate physical activity, BMI, HDL cholesterol, LDL cholesterol, insulin, HOMA-IR, ALT, AST, CRP, BUN, and UA
  5. ALT: alanine transaminase; AST: aspartate aminotransferase; BMI: body mass index; BUN: blood urea nitrogen; CI: confidence interval; CRP: C-Reactive Protein; HDL cholesterol: high-Density Lipoprotein Cholesterol; HOMA-IR, homeostatic model assessment of insulin resistance; LDL cholesterol: low-Density Lipoprotein Cholesterol; OR: odds ratio; PIR:Poverty-to-income ratio; TyG: Triglyceride–Glucose; UA; uric acid
