Fig. 2From: Differential DNA methylation and lymphocyte proportions in a Costa Rican high longevity regionDNA methylation age correlated with chronological age. a Left to right: Horvath age estimation method was used to derive DNA methylation (DNAm) age using 353 CpGs; Hannum method to estimate DNAm age using 71 CpGs, and the Weidner 99 CpG model. b Histogram of age acceleration difference (DNAm age–chronological age). Dotted line shows the mean of all samplesBack to article page
