The KORA F4 study is a population-based cohort of 3,080 subjects living in the southern Germany. Study participants were recruited between 2006 and 2008 comprising individuals with age ranging from 32 to 81. All KORA participants have given written informed consent and the study was approved by the Ethics Committee of the Bavarian Medical Association. For this study, joint data was available for methylation, proteomics, and genotyping measurements of 944 individuals. The DNA methylation data set was determined using the Infinium HumanMethylation450 BeadChip platform which was described in detail previously6 (link). Aptamer-based proteomics was done using the SOMAscan platform and has been described in detail elsewhere2 (link). Genotyping was performed using the Affymetrix Axiom array, also described in detail elsewhere2 (link).
