Validation of the prognostic performance of TNF family-based signature in an independent cohort based on 102 frozen tissues. (a), the distribution of risk score, survival status and gene expression panel. (b), Kaplan–Meier curves of OS in total LUAD (n=102) are stratified by the signature in high- and low-risk groups based on risk score. (c), Kaplan–Meier curves of OS in early-stage (stage I and II) LUAD (n=80) are stratified by the signature in high- and low-risk groups based on the risk score. (d), Kaplan–Meier curves of OS in advanced-stage (stage III and IV) LUAD (n=22) are stratified by the signature in high and low risk groups based on the risk score.
