A Nomogram Model for Individualized Prediction of the Risk of Respiratory Tract Infection within Six Months after Diagnosis in Patients with Primary Immune Thrombocytopenia

Figure 3

External verification of the nomogram model. (a) ROC curve of model evaluation for validation set. (b) Calibration curve of the nomogram model for validation set. The - and -axis represent the actual rate and the predicted risk of respiratory tract infection, respectively. The dotted line represents a perfect prediction made by an ideal model. The red line represents the actual model performance, and the closer it fits to the dotted line, the better the prediction.
