Validation of whole-blood aDMRs in CD14⁺ monocytes and CD4⁺ T-cells from an independent cohort. For each probe with a significant aging-methylation correlation in the whole-blood data (P < 0.01), we calculated Spearman's ρ values from the CD4⁺ and CD14⁺ data sets. We plot 50% and 95% credible intervals for the box-and-whisker plots on bootstrap estimates of the mean for each data set.
