Fig. 2From: Systematic evaluation of DNA methylation age estimation with common preprocessing methods and the Infinium MethylationEPIC BeadChip arrayEPIC DNA methylation age estimated in control samples from the Diesel Exhaust III Study across three tissues. DNA methylation (DNAm) age was estimated using the EPIC 334-CpG model from GenomeStudio background-subtracted and color-channel-adjusted EPIC data. Linear regression line shown with 95% confidence intervals is shown in gray. Error is the median absolute difference between EPIC DNAm age and chronological age. Pearson’s correlation coefficients (r) and corresponding p value are shown for each tissue.
