Computed tomography radiomics-based machine learning nomogram for preoperative prediction of glypican-3 expression in hepatocellular carcinoma

Figure 5 Receiver operating characteristic curves of clinical, radiomics, and combined models in training and testing cohorts. A: Receiver operating characteristic curves for the clinical model, random forest radiomics model, and combined nomogram model in the training cohort, illustrating comparative predictive performance; B: Receiver operating characteristic curves for the clinical model, random forest radiomics model, and combined nomogram model in the testing cohort, demonstrating model performance on independent data. Clinic: Clinical model; ALL: Random forest radiomics model; Nomogram: Combined model; AUC: Area under the curve.
