It can be observed that participants with higher ALT/HDL-C ratios were more likely to be male, MetS patients (Q1: 0.39% VS Q2 1.34% VS Q3 4.75% VS Q4 19.54%), smokers and drinkers, and had a higher prevalence of NAFLD (Q1: 1.66% VS Q2 4.90% VS Q3 15.31% VS Q4 48.40%). This evidence concerns the gene GPT and metabolic syndrome.
