Figure 4. Identification of risk hub genes related to the overall survival of glioma. (A, B) LASSO regression analysis of hub genes in the TCGA cohort. (C) Multivariate Cox regression analysis of hub genes in the TCGA cohort. (D, E) Violin plot showing the expression levels of the 3 risk hub genes between LGG and GBM in the TCGA and CGGA datasets, respectively. (F, G) Kaplan-Meier curves displayed 3 risk hub genes were significantly related to poor prognosis in the TCGA and CGGA datasets, respectively.
