  1. b, p, and q indicate regression coefficient, nominal significance value, and significance level corrected for multiple testing (after correction for genomic inflation), respectively
  2. aAssociation between DNA methylation and HTGW after adjusting for age, age2, sex, age × sex interaction, and age2 × sex interaction, Illumina Sentrix® ID and Sentrix® position (to account for batch effects), use of anti-lipid, anti-hypertensive and anti-diabetic medications and cellular heterogeneity
  3. bAssociation between DNA methylation and HTGW after adjusting for age, age2, sex, age × sex interaction, and age2 × sex interaction, Illumina Sentrix® ID and Sentrix® position (to account for batch effects), use of anti-lipid, anti-hypertensive and anti-diabetic medications, cellular heterogeneity, presence of type 2 diabetes, obesity (body mass index ≥ 30 Kg/m2), systolic and diastolic blood pressure
  4. cMediation estimated using Sobel’s parameter [32]. All regression models were adjusted for age, age2, sex, age × sex interaction, and age2 × sex interaction, Illumina Sentrix® ID and Sentrix® position (to account for batch effects), use of anti-lipid, anti-hypertensive and anti-diabetic medications, and cellular heterogeneity
