The relative risk reduction with catheter ablation vs drug therapy as a function of age as a continuous variable for the primary composite outcome of death, disabling stroke, serious bleeding, or cardiac arrest. The figure shows the adjusted hazard ratio as a solid black line with the 95% confidence intervals represented as the shaded area. The drug arm is used as reference group. aHR=adjusted hazard ratio, CI=confidence interval
