GPT and steatosis: In the multiple linear regression of hepatic OXPHOSmax, using the four independent variables from the simple linear regressions with the lowest P-values (BMI, leptin (P = 0.050), ALT (P = 0.081) and steatosis grade (P < 0.05)), all were positively associated with hepatic OXPHOSmax,) but only BMI proved to be a significant predictor (unstandardised β: 0.0013; 95% CI: 0.0004─0.0021, adjusted R2 = 0.127, P = 0.004).
