Fig. 1From: Genetically predicted dietary macronutrient intakes and atrial fibrillation risk: a Mendelian randomization studyMendelian randomization analyses to investigate associations between relative macronutrient intakes and the risk of atrial fibrillation and flutter. The broken lines signify potential causal effects (pleiotropic or direct) between variables that would violate the assumptions of Mendelian randomizationBack to article page
