  1. β-Estimate is an absolute change in percentage of methylation; slope >(<) 0 means positive (negative) association
  2. aWhen there was no evidence for a differential association between maternal choline intake and DNA methylation at the different CpG locations, the main effect of maternal choline intake over all CpG locations was reported, which was the case for all genes
