(a) Estimated mean DNA methylation level (%5MeC) in OXTR1 amplicons averaged across CpGs at pre-stress, post-stress, and 90 min follow-up stress assessments. Error bars are s.e. of the estimated mean. (b) Differences in individual CpG mean methylation (%5MeC) from pre-stress to post-stress and from pre-stress to follow-up. All estimates obtained from the unadjusted model. *P<0.05.
