¹Over-Expressed Genes: number of genes that have a positive association between expression and glioblastoma multiforme survival.

²Under-Expressed Genes: number of genes that have a negative association between expression and glioblastoma multiforme survival.

³Log Odds Ratio: indicates whether the category is more enriched among the genes that have a positive association between expression and survival relative to the enrichment among the genes that have a negative association between expression and glioblastoma survival (positive log_e odds ratio) or vice versa (negative log_e odds ratio). Extreme values indicate higher difference in the enrichment percentages between the positive and negative association groups meanwhile values close to zero indicate similar enrichment percentages between positive and negative association groups.

⁴FDR-adjusted P-value: False discovery rate adjusted P-value of the log odds ratio test.
