Figure 5. Prognostic analysis of risk score. (A) Kaplan-Meier survival analysis of early-stage LUAD in TCGA high and low risk score group; (B) Time-dependent ROC analysis measuring the predictive value of the risk score in TCGA; (C) Kaplan-Meier survival analysis of early-stage LUAD in GEO high and low risk score group; (D) Time-dependent ROC analysis measure the predictive value of the risk score in GEO; (E) Univariate Cox analysis confirmed that risk score was associated with overall survival in TCGA; (F) Multivariate Cox analysis found that risk score was an independent prognostic factor for early-stage LUAD in TCGA; (G) Correlation between risk score and clinical characteristics.
