After further adjustment for WC, BMI, SBP, DBP, TC, TG, LDL-C, HDL-C, FPG, SUA, Scr, AST, ALT, γ-GGT and TSH, the risk of NAFLD still significantly increased in Q3 group 〔OR=1.255, 95%CI (1.011, 1.559)〕 and Q4 group 〔OR=1.553, 95%CI (1.252, 1.926)〕 comparing with Q1 group (P<0.05) (Model 3) (Table 5). This evidence concerns the gene GPT and metabolic dysfunction-associated steatotic liver disease.
