  1. Results of 62 logistic regressions between methylation M-values and atopy for each selected CpG. We present crude associations as well as associations adjusted for predicted cell proportions of CD8+ T cells, CD4+ T cells, natural killer cells, B-cells, monocytes, and granulocytes. β1 represents the value of the regression coefficient for the CpG site in that statistical model. The percent change in β-values (%Diffβ) was calculated as [(crude β1 – adjusted β1)/crude β1] and was used to evaluate whether cell type influenced the selection of each CpG site
