Figure 1. Kaplan-Meier plots of distant metastasis in high- and low-risk groups (as defined by the BCT score) in the discovery cohort and validation cohort.

Kaplan-Meier plots of distant metastasis at 10 years, between 0–5 years, and at 5–10 years in patients from the discovery cohort (A,C) and validation cohort (B,D). The cutoff value for the BCT score was 4.
