Development and validation of novel nomograms to predict survival of patients with tongue squamous cell carcinoma

Figure 5 Decision curve analysis of the accuracy of the nomograms and tumor-node-metastasis staging system for predicting overall survival and cancer-specific survival in patients with squamous cell carcinoma of the tongue. A: 3-year overall survival (OS) benefits in the training cohort; B: 5-year OS benefits in the training cohort; C: 3-year OS benefits in the validation cohort; D: 5-year OS benefits in the validation cohort; E: 3-year cancer-specific survival (CSS) benefits in the training cohort; F: 5-year CSS benefits in the training cohort; G: 3-year CSS benefits in the validation cohort; H: 5-year CSS benefits in the validation cohort. TNM: Tumor-node-metastasis.
