^†HR: Hazard Ratio; OS: Overall Survival; Q-value = adjusted P-value; TCGA data: N=229; Duke Data: N=51.

Conditional inference trees were used to find optimal cutpoints. Based on cutpoints, the TCGA and Duke “low expression” columns represents the number of patients in the “low expression group” and “high expression” columns represents the number of patients in the “high expression group”.
