From: Identification of an immune signature predicting prognosis risk of patients in lung adenocarcinoma
Multivariate Cox analysis evaluating independently predictive ability of our signature for OS. The signature was able to independently predict patients’ OS in TCGA cohort [Hazard ratio (HR) = 2.1868, 95% confidence intervals (95% CI) 1.7612 to 2.7152, P < 0.001], GSE30219 cohort (HR = 1.6354, 95% CI 1.1632–2.2993, P = 0.0047), and GSE81089 (HR = 1.5156, 95% CI 1.1425–2.0106, P = 0.0039). However, this relationship could not find in GSE31210 (P = 0.4298). TCGA The Cancer Genome Atlas, HR hazard ratio, 95% CI 95% confidence interval
