Development of the nine redox-related lncRNAs signature. (a) Screening of differentially expressed redox-related lncRNAs. (b) Variables going to zero as we increase the penalty (lambda) in the objective function of the LASSO. (c) 10-fold cross-validation for tuning parameter selection in the LASSO model, −4 < lambda.min < −3.5, and there were 20 variables (lncRNAs) left. (d) Results of the multivariate Cox proportional hazard model based on the 20 variables; nine lncRNA genes were screened to construct the signature.
