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 V2 group 〔OR=1.584, 95%CI (1.205, 2.083)〕, V3 group 〔OR=2.386, 95%CI (1.778, 3.202)〕 and V4 group 〔OR=4.104, 95%CI (2.835, 5.939)〕 comparing with V1 group (P<0.01) (Model 3) (Table 6). This evidence concerns the gene GPT and metabolic dysfunction-associated steatotic liver disease.
