Epigenome-wide association studies (EWASs) of six metabolic traits were performed using whole-blood DNA methylation (DNAm) in Generation Scotland with N > 17,000 participants. The first set of EWAS models were adjusted for estimated white blood cells, and an epigenetic smoking score. The second set of EWAS models were further adjusted for the first 20 DNAm principal components. A total of 12 EWAS models were run (2 models per metabolic trait). Authors: Hannah M.
