[Retracted] Establishment of a Risk Prediction Model for Pulmonary Infection in Patients with Advanced Cancer

Figure 4

Decision curve analysis for the nomogram. The -axis measures the net benefit. The blue line represents the nomogram. The green line represents the assumption that all patients have extended operation time. The pink line represents the assumption that no patients have extended operation time. The decision curve showed that if the threshold probability of a patient or doctor is >18%, using the nomogram in the current study to predict extended operation time adds more benefit than the treat-all-patients scheme or the treat-none scheme.
