The receiver operating characteristic curves for each variable in Model III and proposed dynamic nomogram. a The ROC curves for each variable in Model III are shown for the training dataset. The x-axis represents the false positive rate predicted using the model, and the y-axis represents the true positive rate predicted using the model. b A dynamic nomogram was created based on Model III to predict an individual’s risk of developing NAFLD. Based on a patient’s lymphocyte count (1.83 × 10⁹/L), alanine transaminase level (8.9 U/L), triglyceride level (1.39 mmol/L), and body mass index (33.9 kg/m²), the predicted probability of the development of NAFLD was 0.977, indicating that this patient has a 97.7% chance of having NAFLD. BMI, body mass index; ALT, alanine transaminase level; TG, triglyceride level; LYMPH, lymphocyte count; NAFLD, non-alcoholic fatty liver disease; ROC, receiver operating characteristic
