Construction and Validation of a Convenient Clinical Nomogram to Predict the Risk of Brain Metastasis in Renal Cell Carcinoma Patients

Figure 4

Calibration curves of the nomogram for predicting BM in patients with RCC in the training cohort (a) and the validation cohort (b). The -axis represents the nomogram-predicted probability of BM; the -axis represents the actual probability of BM. Plots along the 45-degree line indicate a perfect calibration model in which the predicted probabilities are identical to the actual outcomes.
