In multivariable models, BMI (OR 1.09; <i>p</i> < 0.001) and metabolic syndrome (OR 3.34; <i>p</i> < 0.001) were independently associated with MASLD, while BMI (OR 1.02; <i>p</i> < 0.001), metabolic syndrome (OR 2.03; <i>p</i> = 0.015), and ALT (OR 1.02; <i>p</i> = 0.032) were independently associated with fibrosis. This evidence concerns the gene GPT and metabolic syndrome.
