Figure 1. — Plots of epigenetic age acceleration analysis. (a) Scatter plot of the relationship between chronological age and DNA methylation age. (b) Bar graph of universal epigenetic age acceleration comparison between SCA and NCA. (c) Bar graph of IEAA compare son between SCA and NCA. (d) Bar graph of EEAA comparison between SCA and NCA. NCA = normal cognitive aging; SCA = successful cognitive aging; IEAA = intrinsic epigenetic age acceleration; EEAA = extrinsic epigenetic age acceleration. ^# p < .05 versus NCA group.
