Figure 7. Mutation analysis of the DRG-lncRNAs based on the risk score model. (A, B) The waterfall diagram shows the genes that most frequently undergo somatic mutations under different risk groups. (C) The difference in tumor mutation burden between high- and low-risk score groups. (D) Kaplan-Meier curves of high and low TMB groups. (E) Kaplan-Meier curves of four groups classified by risk score and TMB. Abbreviations: DRG-lncRNAs: disulfidptosis-related long non-coding RNAs; TMB: tumor mutational burden; H: high; L: low.
