  1. aModel adjusted for age, smoking, and residuals of plasma folate, plasma vitamin B-6, and plasma vitamin B-12; forward strand allele shown.
  2. bNo FDR-adjusted P values reached False Discovery Rate significance threshold of 0.05.
  3. cEffect represents per genotype change in LINE-1 element methylation standard deviation.
  4. dNo sparse data (fewer than 5 individuals per category) for any genotype categories of these SNPs.
  5. eNo SNPs map to more than one gene.
  6. fNo lower quality SNPs.
  7. gD:Dominant; R:Recessive; A:Additive; O:Overdominant.
