Figure 4 Validation of the nomogram: A: Validation using the area under the receiver operating characteristics curve; B: Calibration curve for verifying the consistency between the predicted probabilities and the actual observed probabilities; C: Decision curve analysis to assess the clinical efficacy of the model. AUC: Area under the receiver operating characteristics curve.
