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 2

Internal verification of the nomogram model. (a) Risk of respiratory tract infection within six months after diagnosis in patients with primary immune thrombocytopenia by ROC curve. (b) Calibration curve of the nomogram model for training 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.
