From: Nomograms to predict survival after colorectal cancer resection without preoperative therapy
Kaplan–Meier curve analysis of risk classification and stratification in the training cohort. a Risk classification of CSS and OS using the 7th edition of the AJCC stages (AJCC7) and Nomo stages (all log-rank P values for trend <0.0001). b Risk stratification of CSS for each AJCC7 substage. c Risk stratification of OS for each AJCC7 substage (all log-rank P values for trend <0.0001, all log-rank P values for pairwise comparisons <0.05). CSS, cancer-specific survival; OS, overall survival; AJCC, American Joint Committee on Cancer
