Setting AHR in sinus rhythm state into three tertiles, we also observed a trendof increasing AHR being associated with a decreasing risk of AF recurrence inModel 0, Model I, and Model II regression equations (OR: 0.242, 95% CI:0.065–0.908, p = 0.035; OR: 0.099, 95% CI: 0.017–0.559, p =0.009; and OR: 0.025, 95% CI: 0.001–0.742, p = 0.033; respectively). This evidence concerns the gene AHR and atrial fibrillation.
