The construction and assessment of the nomogram. (A) The nomogram to predict the 1-, 3-, and 5-yr survival of colorectal cancer (CRC) patients. (B) Time-dependent receiver operating characteristic (ROC) curves for 1-, 3-, and 5-yr overall survival (OS) predictions by the nomogram. (C) The calibration curves for predicting 1-, 3-, and 5-yr OS by the nomogram. The closer the distance from the colored solid lines to the dotted line, the better the consistency between the predicted results and the actual results. (D) Of the nomogram, age, and AJCC stage, which showed the nomogram performed better clinical benefit than AJCC stage and age. AJCC = American Joint Committee on Cancer.
