Development of a multi-lncRNAs based classifier. (A) The expression heat map of the top 20 down- and up-regulated differently expressed lncRNAs between low- and high-TMB groups. (B and C) Optimal lncRNAs selection in the LASSO regression model. (DF) Receiver operating characteristic analyses in the training, validation, and pooled set. (G) Receiver operating characteristic analyses of multi-lncRNAs based classifier index and clinical characteristics. (H) The correlation between the classifier index and TMB.
