BCR and major depressive disorder: Table 4 shows list of PTSD-unique and MDD-unique gene list with hyper- and hypo-methylated cytosine sites. The conversion rate averaged over all the samples is 0.9977 with standard deviation of 0.0011 as calculated by BCR calculator (Zhou et al., 2020). The number of CpG sites was 28.3 million as calculated by Luo et al. (2014), and the number of CpG sites in the promoter region is 3,937,537 sites.
