Figure 2. Prognostic signature based on 14 hub genes. (A) Differentially expressed genes in TCGA between low-fibroblast group and high-fibroblast group. (B, C) LASSO-COX analysis of prognostic genes. (D) The OS is shorter in the high-risk group than in the low-risk group in TCGA. (E) The OS is shorter in the high-risk group than in the low-risk group in GSE39582. (F) The OS is shorter in the high-risk group than in the low-risk group in TCGA and GSE39582.
