Construction and validation of a novel prognostic nomogram for patients with poorly differentiated gastric neuroendocrine neoplasms

Figure 1 Comparison of overall survival among stage I, stage II, stage III and stage IV patients. OS: Overall survival.

Figure 2 Nomogram prediction model. A: Nomogram prediction model for 1-year, 3-year, and 5-year overall survival in patients; B: Receiver operating characteristic for the nomogram prediction model. PLR: Platelet-to-lymphocyte ratio; OS: Overall survival; AUC: Area under the curve.

Figure 3 Calibration curve for the nomogram prediction model. OS: Overall survival.

Figure 4 Decision curve analysis of nomogram prediction model and American Joint Committee on Cancer (8^th edition) tumor-node-metastasis staging system. A: 1-year overall survival (OS); B: 3-year OS; C: 5-year OS. TNM: Tumor-node-metastasis.
