Logistic regression analysis of all risk factors of NAFLD. Abbreviations: ALT, alanine aminotransferase; AST, aspartate aminotransferase; HBP, High blood pressure; HDL, high density lipoprotein; HUA, hyperuricemia; LDL, low-density lipoprotein; SBP, systolic blood pressure; SUA, serum uric acid; TG, triacylglycerol. NAFLD was defined as: 0 for no fatty liver, 1 for mild fatty liver, and 2 for moderate and severe fatty liver. Sex was coded as: 0 for male, 1 for female. HUA is defined as SUA > 420 μmol/L in male, and >360 μmol/L in female. Abnormal AST is defined as AST > 40 IU/L, Abnormal ALT is defined as ALT > 40 IU/L. Low-HDL is defined as HDL-c < 0.90 in men or <1.00 in women. High LDL is defined as LDL-c ≥ 2.6 mmol/L. High TG is defined as TG ≥ 1.7 mmol/L. Central obesity is defined as waist > 90 cm in men and >80 cm in women. HBP is defined as blood pressure ≥ 140/90 mmHg. Age1 is defined as age ≥ 20y and <30y; Age2 is defined as age ≥ 30y and <40y; Age3 is defined as age ≥ 40y and <50y; Age4 is defined as age ≥ 50y and <60y; Age5 is defined as age ≥ 60y
