From: DNA methylation links prenatal smoking exposure to later life health outcomes in offspring
Longitudinal analysis of association between exposure to maternal smoking and offspring blood DNA methylation. Effect size estimates (adjusted for study-specific covariates and meta-analyzed using inverse-variance weighted fixed-effects model) and their 95% confidence intervals at age 30–31 years (red) and age 46–48 years (blue) for top CpG sites and P values for the test of equality of the effect size estimates
