Figure 1From: Birth weight and the risk of atrial fibrillation in whites and African Americans: the Atherosclerosis Risk In Communities (ARIC) study Causal model for the association of birth weight, as a proxy for intrauterine growth restriction, with the incidence of atrial fibrillation. The red-dashed line represents a hypothetical direct effect of intrauterine growth retardation on atrial fibrillation incidence not mediated through known cardiovascular risk factors. CVD: Cardiovascular disease. SES: Socioeconomic status.Back to article page
