Establishment of a risk assessment model using DEirlncRNA pairs. Identification of differentially expressed immune-related lncRNAs (DEirlncRNAs) using TCGA datasets and annotation by Ensembl. (a and b) The heat map (a) and volcano plot (b) are shown. (c) Variables going to zero as we increase the penalty (lambda) in the objective function of the LASSO. (d) 10-fold cross-validation for tuning parameter selection in the LASSO model, −4 < lambda.min < −3.5, and there were 28 variables (immune-related lncRNA pairs) left. (e) The univariate Cox regression analysis of the 12 DEirlncRNA pairs. (f) A forest map shows 12 DEirlncRNA pairs identified by the Cox proportional hazard regression in the stepwise method.
