The nomogram model analysis. a The predictive weight of each factor and prognostic risk score in predicting the prognosis of colon cancer. The red line with arrow notes the 3- and 5-year survival probability of the example case. b The difference analysis between nomogram-predicted survival probability and the actual survival. The nomogram-predicted survival probabilities have high compliances with the actual situations (c-index = 0.752 and 0.721)
