Figure 2. Risk score calculated by using nine hub-telomere-related genes (TRGs) in LUAD. (A) Volcano plot showing the significant genes and hazard ratio values in univariate COX regression analysis. (B) Survival curves of high and low TRG risk score groups plotted by K-M method. (C) Boxplots of nine hubTRGs mRNA expression in LUAD. (D) and (E) Boxplots and immunohistochemistry staining of the nine hub-telomere-related proteins in LUAD and normal control.
