¹IEAA measured using CPGs from the Hannum epigenetic clock

²IEAA measured using CPGs from Horvarth DNAmAge epigenetic clock

³EEAA measured using CPGs from Hannum epigenetic clock, adjusted for the proportion naive CD8 + T cells, memory CD8 + cells, and plasmablasts

⁴EEAA measured using CPGs from Horvath DNAmAge epigenetic clock
