CpGs associated with cortisol levels in epigenome‐wide analysis. Plots (a) to (d) show correlation between methylation and continuous levels of cortisol. (a) cg15321696 (r = −0.33, p = 0.0002, Benjamini‐Hochberg (BH) Adj.p = 0.078), (b) cg18105800 (r = 0.33, p = 0.0003, BH. Adj.p = 0.11), (c) cg00986889 (r = −0.25, p = 0.006, BH. Adj.p = 0.11), (d) cg15920527 (r = −0.27, p = 0.003, BH. Adj.p = 0.11). BH. Adj.p = p value after adjustment for estimated blood cell proportions, child age and sex, maternal age, education, marital status, location and prenatal smoking status, batch effects, and multiple testing with a cut off of p < 0.15. P = preadjusted significance of correlation/association. R = preadjusted correlation coefficient. Y‐axis represents % methylation
