Non-linear association of the alanine aminotransferase to high-density lipoprotein cholesterol ratio with non-alcoholic fatty liver disease: a secondary analysis of a Chinese cohort

The ALT/HDL-C ratio is independently and nonlinearly associated with NAFLD in Chinese adults, with a particularly strong association in non-elderly individuals and women. This simple and readily available biomarker shows promise for enhancing NAFLD risk stratification in middle-aged adults, while its utility in the elderly population may be limited and requires further investigation.
