Fig. 2: Panel A shows estimates of the proportion of patients with no recurrence of atrial fibrillation in the group taking amiodarone and in the group assigned to sotalol or propafenone (hazard ratio for recurrence among patients in the amiodarone group 0.43 [95% confidence interval 0.32–0.57]); panel B shows the estimates for the 350 patients (187 in the amiodarone group and 163 in the group assigned to sotalol or propafenone) who were in sinus rhythm 21 days after randomization (hazard ratio 0.45, 95% confidence interval 0.32–0.63); and panel C shows the estimates for the patients who received amiodarone, those who received sotalol and those who received propafenone. Follow-up began 21 days after randomization (designated day 0). Reprinted with permission from the Massachusetts Medical Society (N Engl J Med 2000;342:913-20).³⁸
