As shown in Table 2, for ALT > 26 U/L, which may be used to screen for NAFLD, multiple logistic regression analysis revealed that the decrease among the MFR tertiles was significantly higher (p < 0.05) in Model 1 [age], Model 2 [age, obesity (BMI > 25 kg/m2)], Model 3 [age, obesity (BMI > 25 kg/m2), muscular fitness], Model 4 [age, obesity (BMI > 25 kg/m2), metabolic risk factors (FBS, TG, HDL-C)], and Model 5 [age, obesity (BMI > 25 kg/m2), muscular fitness, metabolic risk factors (FBS, TG, HDL-C)]. Here, GPT is linked to obesity disorder.
