Figure 1. Molecular classification based on aging-related lncRNAs. (A) The flow chart of data analyses in the study. (B) The circle plot showed the correlation among 33 aging-related lncRNAs. (C) Glioma patients were divided into three clusters in CGGA. (D) PCA indicated that three subclasses were obtained in CGGA. (E) Three subclasses were validated in TCGA. (F) Kaplan-Meier cures of overall survival for three clusters in CGGA. (G) Kaplan-Meier cures of overall survival for three clusters in TCGA.
