Fig. 5From: Nomograms to predict survival after colorectal cancer resection without preoperative therapyBootstrap calibration of nomograms in the external cohorts. The nomograms were externally calibrated in the validation cohort by predicting the 3- and 5-year (a, b) CSS and (c, d) OS. The nomograms were also calibrated in the test cohort for the 3-year (e) CSS and (f) OS. All results showed good validation. CSS, cancer-specific survival; OS, overall survivalBack to article page
