Figure 5From: Test on existence of histology subtype-specific prognostic signatures among early stage lung adenocarcinoma and squamous cell carcinoma patients using a Cox-model based filter Kaplan-Meier curves between high-risk and low-risk groups using 32-, 15-, 13-gene prognostic signatures with selected genes as covariates in risk score construction. Patients were stratified into high-risk and low-risk groups for death on the basis of their risk scores. The cutoff was set at the mean value of those risk scores. Log-rank tests were used to compare the survival profiles of the high-risk and low-risk groups. All p-values of those tests were <0.05.Back to article page
