  1. Data are shown as the mean change in methylation levels (%) between baseline and 36 months after treatment (calculated as post–pre) for the four treatment groups
  2. aChromosome and position (base pair) are based on build 37 (hg19) of the human genome reference sequence
  3. bp-values are derived from tests of interaction between time-since-menopause and HT using M-values for methylation with adjustment for age, ethnicity, and estimated blood cell fractions
  4. S_Shelf, southern shelf region that is directly adjacent to a southern shore, which is directly downstream of a CpG island
