Figure 2. Establishment and validation of the eight-lincRNA prognostic signature. (A) The procedure of the establishment of the prognostic signature. (B–C) Correlation between the prognostic signature and the overall survival of patients in the GEO cohort (B) and TCGA (C) cohorts. The distribution of risk scores (upper), survival time (middle) and lincRNA expression levels (below). The black dotted lines represent the median risk score cut-off dividing patients into low- and high-risk groups. The red dots and lines represent the patients in high-risk groups. The green dots and lines represent the patients in low-risk groups.
