Figure 1
Figure 1 Nomogram for predicting overall survival rate of colorectal cancer patients after surgery. The nomogram incorporated race, T stage, log odds of positive lymph nodes, M stage, age, carcinoembryonic antigen, and tumor deposit. It predicted the overall survival at 1, 3, and 5 years after surgery. CEA: Carcinoembryonic antigen; LODDS: Log odds of positive lymph nodes; TD: Tumor deposit.

A: 1-year overall survival (OS) rate predicted by the nomogram in the training set; B: 3-year OS rate predicted by the nomogram in the training set; C: 5-year OS rate predicted by the nomogram in the training set; D: 1-year OS rate predicted by the nomogram in the validation set; E: 3-year OS rate predicted by the nomogram in the validation set; F: 5-year OS rate predicted by the nomogram in the validation set.
