Epidemiology and prognostic nomogram for locally advanced gastric signet ring cell carcinoma: A population-based study

Figure 11  Validation of the nomogram's training set. A: Receiver operating characteristic curves for 1-, 3- and 5-year overall survival (OS) in the training set; B: Calibration curves for 1-, 3- and 5-year OS in the training set; C: Decision curves of the nomogram for predicting 1-, 3- and 5-year OS in the training set. AUC: Area under the receiver operating characteristic curve; OS: Overall survival; TP: True positive rate; FP: False positive rate.
