From: Nomogram for individually predicting overall survival in rectal neuroendocrine tumours
The calibration of the nomogram in the training and validation sets. The x-axis represents the survival rate predicted by the nomogram, whereas the y-axis presents the actual survival rate. The 95% CIs were measured via a Kaplan-Meier analysis. All predictions lie within a 10% margin of error. a 1-year OS in the training set. b 3-year OS in the training set. c 1-year OS in the validation set. d 3-year OS in the validation set
