Figure 5.

The correlation between methylation level and cytosine allele frequency. The X-axis includes five classes of CpG sites defined on the basis of their cytosine allele frequency. The Y-axis is the methylation level that was computed as the number of methylated reads over the total number of reads mapped to each cytosine base. The correlation coefficient (r2) is shown on the plot.
