Nomogram based on clinical characteristics for predicting overall survival in gastric cancer patients with preoperative anemia

Figure 1  Flowchart of patient selection.

Figure 2  Patient survival analysis.

Figure 3 Nomogram for predicting the 1-, 3-, and 5-year overall survival of patients with preoperatively anemic gastric cancer. OS: Overall survival.

Figure 4 Receiver operating characteristic curve of the nomogram. A-C: 1- (A), 3- (B), and 5-year (C) overall survival in the training group; D-F: 1- (D), 3- (E), and 5-year (F) overall survival in the validation group. AUC: Area under the receiver operating characteristic curve.

Figure 5 Calibration curves of the nomogram. A-C: 1- (A), 3- (B), and 5-year (C) overall survival in the training group; D-F: 1- (D), 3- (E), and 5-year (F) overall survival in the validation group. OS: Overall survival.

Figure 6 Decision curve analysis of the nomogram. A-C: 1- (A), 3- (B), and 5-year (C) overall survival in the training group; D-F: 1- (D), 3- (E), and 5-year (F) overall survival in the validation group.
