Figure 1. Miami plots. P values based on meta-analysis results of the associations between cord blood or mid-childhood peripheral blood DNA methylation with mid-childhood atopic sensitization, environmental and food allergen sensitization.
Redline – Bonferroni significance (Bonferroni-adjusted p-value<0.05)Green line – FDR significance (FDR-adjusted p-value <0.05)

Table 4. Regional analysis (comb-p) of the association between mid-childhood peripheral blood with mid-childhood atopic sensitization and environmental allergen sensitization.
Figure 4. Trajectory plots of methylation changes by atopic status. Methylation sites were selected as they showed nominal significance in the cord blood analysis, and epigenome-wide significance in the mid-childhood analysis. Top 4 plots: top 4 methylation sites sorted by cord blood p-values based on the criteria described above; bottom 4 plots: methylation sites previously shown to be associated with asthma.
