GPT and steatosis: The large multicentre study showed that FLI (like ALT), discriminated between patients with and without steatosis with an area under ROC (AUROC) of 0.79 (inter-quartile range (IQR) = 0.74, 0.84), accurately matched the observed percentages of patients with hepatic steatosis, although it could not quantitatively predict fatty liver disease [49].
