Manhattan plots from the epigenome-wide association studies performed in three European birth cohorts of childhood allergic disease (discovery). A total of 439,306 CpGs were tested for association. The red dotted horizontal line represents the Bonferroni-corrected threshold (p<1.14 × 10–7) of genome-wide significance. All 21 replicated CpGs are marked as green circles and annotated with CpGs name. (A) Results for the EWAS analysis in children aged 4 years (n=636) from the three European cohorts BAMSE, INMA and PIAMA. (B) Results for the EWAS meta-analysis in children aged 8 years (n=821) from BAMSE and PIAMA.
