Calibration curves for 1-, 3-, and 5-year nomogram predictions. The calibration curves for predicting overall survival (OS) in colorectal cancer (CRC) patients at (a) 1, (b) 3, and (c) 5 years in the training set and at (d) 1, (e) 3, and (f) 5 years in the validation set. The calibration curves for predicting disease-free survival (DFS) in CRC patients at (g) 1, (h) 3, and (i) 5 years in the training set and at (j) 1, (k) 3, and (l) 5 years in the validation set.
