Univariate and multivariate Cox analyses for the signature-based risk score and other clinical features. (a) A univariate Cox regression analysis validated the signature-based risk score as a predictive factor for the TCGA-LUAD and GSE72094 cohorts. (b) A multivariable Cox regression analysis validated the signature-based risk score as an independent predictive factor for the training cohort and two external validation cohorts.
