Development and Validation of a Prediction Model of the Risk of Pneumonia in Patients with SARS-CoV-2 Infection

Figure 3

(a) Nomogram of the pneumonia risk model; (b–g): ROC curves (bootstrap = 500 times), calibration curves, and DCA curves of the pneumonia risk model in the training and validation cohorts. The ROC curves show good discrimination of the pneumonia risk model in both the training and validation cohorts. The calibration curves showed that the pneumonia risk model has good calibration accuracy. The decision curve analysis showed that the pneumonia risk model has high clinical value in predicting the probability of pneumonia in SARS-CoV-2-infected patients.
