When replacing the presence of hepatic steatosis according to the HRI with ALT levels, the positive association between the disposition index and MQI remained significant (β: 0.069, SE: 0.022, p = 0.004), but no significant association was found between ALT concentrations and MQI (Table 3) Analogous findings were obtained when including γGT levels in place of either hepatic steatosis or ALT concentrations (β: 0.065, SE: 0.023, p = 0.008) (Table 4). Here, GPT is linked to fatty liver disease.
