In prediction models developed for the general population, frequently used predictors also included (descending order by frequency): diabetes (17/32), alcohol (15/32), smoking (13/32), physical activity (12/32), alanine aminotransferase (ALT) (15/32), aspartate aminotransferase (AST) (11/32), and gamma-glutamyl transferase (GGT) (9/32). Here, GPT is linked to diabetes mellitus.
