Fig. 2From: Comparative analysis of histologically classified oligodendrogliomas reveals characteristic molecular differences between subgroupsOligodendroglioma subgroup comparison. a Pearson correlation between the expression log-ratios of 756 marker genes in the Verhaak glioma reference set and our tumor subgroups is shown for the four Verhaak classes. b Pearson correlation between the expression log-ratios of 42 genes in the G-CIMP reference set and our tumor subgroups. c Kaplan-Meier curves (solid lines) and 95%-confidence intervals (dashed lines) of patient survival according to the corresponding clinical dataBack to article page
