The AUROC of the seven-parameter nomogram model including WHtR, age, TyG-WC, ALT, TC, ApoB, and HOMA-IR for predicting female NAFLD was 0.810 (95% CI 0.782–0.837, p < 0.001) (Supplementary Figure S1). This evidence concerns the gene APOB and metabolic dysfunction-associated steatotic liver disease.
