Natural cubic splines for the association of (A) PRAL, (B) NEAP, and (C) A:P with the predicted probability of NAFLD in (metabolic) model 3. (A) Model with PRAL vs model without PRAL (P = 0.038). (B) Model with NEAP vs model without NEAP (P = 0.015). (C) Model with A:P vs model without A:P (P = 0.012). The y-axis represents predicted probability of NAFLD in (metabolic) model 3: NAFLD ∼ DAL proxy + age + sex + education level + energy intake + study cohort + smoking + units of alcohol + physical activity + HDL cholesterol + triglycerides + metabolic syndrome + GFR + diabetes mellitus + BMI. The x-axis represents values of PRAL, NEAP, or A:P. The gray-colored bar represents the 95% CI. The upper and lower 2.5th percentile were excluded from the graphs.
