Representative scatter plots of methylation values of tested genes with different high-risk variables. Methylation levels of GSTP1, APC, CCND2, MGMT, P16, and RARβ2 in plasma DNA of different groups. Calculation of the gene of interest: ratios were based on the fluorescence emission intensity values for both the gene of interest and β-actin obtained by quantitative real-time PCR analysis. The obtained ratios were multiplied by 1,000 for easier tabulation. Values designated as 0.01 are zero values, which cannot be plotted correctly on a log scale.
