GPT and metabolic dysfunction-associated steatotic liver disease: Table 1 shows the clinical characteristics and biochemical measurements of the population studied. Levels of age, HbA1c, TG, AST, and ALT were significantly higher in the NAFLD group than in the simple obesity group (all P < 0.05). Moreover, the level of HDL-C was significantly lower in the NAFLD group than in the simple obesity group (P = 0.004). In terms of sex, BMI, WHR, SBP, DBP, FBG, FINS, HOMA-IR, TC, LDL-C, total bilirubin, WBC, hematocrit, and albumin, no significant differences were found between the two groups (all P > 0.05).
