Heatmap showing the SNP-CpG mapping. Each row and column represents a CpG probe and depression risk locus, respectively. Those tests that are not significant after Bonferroni correction are left blank. For those significant associations, a darker cell represents a higher −log10-transformed p-value. All CpG probes and depression risk loci were categorised based on which chromosome (CHR) they locate. Within each chromosome, probes and SNPs are aligned from left to right or from bottom to top based on their genomic position
