DNA methylation of 10 candidate biomarkers. a DNA methylation levels, measured by PRM, of ten markers TWIST1, VAV3-AS1, FBN1, C9orf50, SFMBT2, KCNQ5, FAM72C, ITGA4, KCNJ12 and ZNF132 in 71 non-CRC samples and 197 CRC samples. * p < 0.05; ** p < 0.01; *** p < 0.001. b Correlation of DNA methylation levels in CRC plasma samples of the 10 markers. Blue, positively correlated; Red, negatively correlated
