<p>The study examined the association between DNA methylation age and mortality. Methylation age was estimated in 4 cohorts (including the Lothian Birth Cohorts of 1921 and 1936) and related to subsequent time-to-death. Across all four cohorts there was a strong correlation between predicted methylation age and chronological age. For individuals with a 5 year age acceleration (DNA methylation age - chronological age = 5), there was a meta analysed hazard ratio of mortality of 1.21 [1.14, 1.29]. Phenotype data associated with the study are available through dbGaP, the methylation raw data are available through the European Genome-phenome Archive (<a href="https://www.ebi.ac.uk/ega/home">EGA</a>; accession number EGAS00001000910).</p>
