NAFLD was introduced as a dependent variable in the multiple factors logistic regression analysis models (Fig. 3), using sex, hypertension (HBP), central obesity, hyperuricemia (HUA), high-LDL, high-TG, low-HDL, abnormal ALT, and abnormal AST (both classified as yes or no), and age (divided into groups, higher age groups was compared with the lowest age group) as independent variables. Here, GPT is linked to hyperuricemia.
