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

Figure 8 Calibration curves for the training and testing cohorts. A: Calibration curve of the model in the training cohort, illustrating the agreement between predicted and observed probabilities; B: Calibration curve of the model in the testing cohort, demonstrating the model’s calibration performance on independent data. Clinic: Clinical model; ALL: Random forest radiomics model; Nomogram: Combined model.
