In a cross-sectional study of an adult health checkup cohort, the TyG–ALT index obtained by multiplying the TyG index by ALT was superior to the TyG index in detecting NAFLD, with an AUC of 0.805.[39] A study on the usefulness of the modified TyG index by applying ALT to the TyG index in children and adolescents has not been reported yet. This evidence concerns the gene GPT and metabolic dysfunction-associated steatotic liver disease.
