Genetics of height and risk of atrial fibrillation: A Mendelian randomization study

Background Observational studies have identified height as a strong risk factor for atrial fibrillation, but this finding may be limited by residual confounding. We aimed to examine genetic variation in height within the Mendelian randomization (MR) framework to determine whether height has a causal effect on risk of atrial fibrillation. Methods and findings In summary-level analyses, MR was performed using summary statistics from genome-wide...
