Figure S2: Volcano plot showing methylation status of previously reported genes in our samples. The Delta β is shown on x-axis and ANOVA p-value on the y-axis. A: represents the 245 loci covering the previously reported genes mainly from candidate gene approach-based studies; B: represents the 376 loci covering the 132 genes reported from a single study based on genome-wide approach (although testing only 1505 CpG sites). The side bar shows the color scale depending on Delta β where blue indicates hypomethylation and red indicates hypermethylation in CRC.
