Construction, Validation, and Visualization of Two Web-Based Nomograms to Predict Overall and Cancer-Specific Survival in Patients with Gastric Cancer and Lung Metastases

Figure 4

Receiver operating characteristic (ROC) curves of cancer-specific survival (CSS). (a–c) ROC curves corresponding to 3, 6, and 12 months in the training cohort, respectively; (d–f) ROC curves corresponding to 3, 6, and 12 months in the verification cohort, respectively; (g) the time-dependent ROC curve corresponding to 1 to 12 months in the verification cohort in the training cohort; (h) the time-dependent ROC curve corresponding to 1 to 12 months in the verification cohort. ROC, receiver operating characteristic; CSS, cancer-specific survival.
