Table S1. - Correlation coefficients of methylation status between each CpG site and Alu clone subgroups with various methylated CpGs. All of 427 Alu clones were classified into different subgroups according to the methylated-CpG number. Average methylation frequency of each CpG site within each Alu subgroup was calculated (methylated-CpG number of the CpG site to the clone number of Alu within the subgroup). The correlation coefficient was calculated for each CpG site based on the corresponding average methylation frequency within each subgroup and the total methylated-CpG number within the subgroup.
