Figure 3. The analyses of HMG-box related DEmRNAs co-expressed lncRNA. Principle component analysis (PCA) of HMG-box related DEmRNAs was shown in (A), PCA analysis for co-expressed lncRNA in (B); PCA analysis for risk lncRNA was shown in (C). (D) Heatmap of risk lncRNA among high and low risk groups. (E) The distribution of co-expressed lncRNA survival status and survival time in model group. (F) Forest plot drawing for the independent prognostic value of risk lncRNAs extracted from univariate Cox regression analysis. (G) The survival curves of GBM patients in model group.
