GATIS score for predicting the prognosis of rectal neuroendocrine neoplasms: A Chinese multicenter study of 12-year experience

Figure 4 Nomogram validation for progression free survival prediction. A: Calibration plot of 3-year progression free survival (PFS) for the training set; B: Calibration plot of 5-year PFS for the training set; C: Calibration plot of 3-year PFS for the validation set; D: Calibration plot of 5-year PFS for the validation set; E: The decision curve analysis for PFS; F: Time-dependent area under the receiver operating characteristic curve analysis for PFS. PFS: Progression free survival; PNI: Prognostic nutritional index; AUC: Area under the receiver operating characteristic curve.
