Table 5 Differentially methylated positions (DMPs) and differentially variable positions (DVPs) in meta-analyses. DMPs and DVPs (FDR < 0.05) in the PBMC meta-analysis (i.e., including the Chile PBMC study, Bangladesh 450 K study, and Bangladesh 850 K study) and PBMC + buccal cell meta-analysis (i.e., including the Chile buccal cell study) adjusted for age, smoking status, cell type proportions, and sex (in the Chile studies). CpGs identified in multiple meta-analyses are bolded

From: Exposure to arsenic at different life-stages and DNA methylation meta-analysis in buccal cells and leukocytes
