Conventional prediction models showed that baseline BMI, in addition to age, sex, smoking, and drinking, explained 13% (8%–19%) of the 5‐year variation in liver fat concentrations, and the addition of biochemistry‐measured HDL cholesterol, triglycerides, alanine transaminase, and a history of diabetes further explained 1% to 7% of the variation in liver fat concentrations (Supporting Information Table S5). Here, GPT is linked to diabetes mellitus.
