  1. The model is adjusted for sex, age, smoking, WBCs, technical covariates, BMI and alcohol consumption. The epigenome-wide significance threshold for association of DNA methylation sites with coffee consumption sets at 1.1 × 10−7 (after Bonferroni correction for multiple testing 0.05/450,000).
  2. CpG DNA methylation site, CHR chromosome, Gene annotated gene, NA not annotated, β effect estimate, SE standard error, I2 heterogeneity.
