FIGURE 5.

Correlation between DNA methylation and survival outcomes. (A) Spearman correlation was used to measure linear relationships between DNA methylation and gene expression levels. Statistically significant expression difference (log‐rank p‐value < 0.05) were found in eight genes. x‐axis: gene expression levels; y‐axis: DNA methylation levels. (B) Kaplan–Meier curves presenting the association of eight genes methylation and survival outcomes. Statistically significant survival difference (log‐rank p‐value < 0.05) were found in eight genes. x‐axis: Day; y‐axis: probability of overall survival. (C) Association of eight gene expression and survival outcomes. Red indicates the high methylation level or expression level; green indicates the low methylation level or expression level
