Heatmap of the methylation β-value ratio between tumor and non-tumor tissues for the 44 genes in our cohort. Heatmap of the methylation β-value ratio between tumor and non-tumor tissues (T/N ratio) for 44 genes that were determined to be specifically hypermethylated in GC tumors in the TCGA cohort. The T/N ratio is expressed asāāā1.2 to 1.2 by ordinary logarithmic conversion.
