Figure 1. Number of differentially methylated CpG (cytosine-guanine dinucleotide) sites by child’s gender, maternal v paternal report of stressors, and during the infancy v preschool period.

The Figure is a visual display of data summarized in Table 1 for HCSs with increased methylation by parental stress (shown above the horizontal zero line) and with decreased methylation by parental stress (shown below the line). The figure also distinguishes sites with greater than 5% difference in methylation comparing low and high stress groups.
