Figure 4. Construction and validation of a nomogram based on the CHRDL1. (A) nomogram to predict survival probability at 1, 3, and 5 years for LUAD patients. The C-index for the nomogram was 0.752(CI=0.727-0.776) with 1000 bootstrap replicates. (B) Calibration curve with the Hosmer-Lemeshow test of the nomogram in the TCGA-LUAD cohort.
