Fig. 5

The scatter plots of gene expression variation and DNA methylation variation for CpG markers located within the core sub-regions of the putative promoters. In this figure, only the CpG markers within the core sub-region (Fig. 3) were included in this analysis. Therefore, the data presented in this figure is a subset of the one presented in Fig. 4. The Both, Upstream, and Downstream columns individually represented the − 1500 to + 500 bp, − 1500 to − 1 bp and + 1 to + 500 bp regions. The sample sizes for sub-figures a to i were in order: 17,891, 2735, 40,106, 13,298, 1868, 27,482, 4593, 867, and 12,624
