Figure 4. The methyltransferase-related IncRNAs signature was a prognostic biomarker for OS in the TCGA-LUAD cohort. (A) K-M survival of OS according to methyltransferase-related IncRNA signature groups in the training cohorts; (B) AUC of time-dependent ROC curve for the risk score in the training dataset; (C) The OS status and OS risk score plots in the training dataset; (D) The heat map of these 6 methyltransferase-related lncRNAs between the high- and low-risk groups in the training dataset; (E) K-M survival of OS according to methyltransferase-related IncRNA signature groups in the test cohorts; (F) AUC of time-dependent ROC curve for the risk score in the test dataset; (G) The OS status and OS risk score plots in the test dataset; (H) The heat map of these 6 methyltransferase-related lncRNAs between the high- and low-risk groups in the test dataset.
