    Reply to comment "Dose-response relationship between caffeine and risk of atrial fibrillation"

    We thank Yan Qu and colleagues for their interest in our publication.1 In our systematic review we concluded that caffeine exposure was not associated with increased AF risk. We also have performed a qualitative evaluation of dose-response, which uses the relative proportions of caffeine exposure within each study and the risk of atrial fibrillation (AF). Pooling the relative risk (RR) of low caffeine intake from each st...
