  2. IEAA, intrinsic epigenetic age acceleration; EEAA, extrinsic epigenetic age acceleration; SBP, systolic blood pressure; DBP, diastolic blood pressure; MAP, mean arterial pressure; PP, pulse pressure; HDL-C, high density lipoprotein; LDL-C, low density lipoprotein
  3. Effect sizes (β) correspond to the change in the cardiometabolic risk factor associated with a 1-year increase in the epigenetic age acceleration measure
  4. Associations significant at P < 0.05 are shown in bold; †Associations significant at Bonferroni adjusted P < 0.005
