The hazard ratio (HR) for achieving a hospital episode when comparing AVATAR protocol arm to drug therapy is 0.156 (95% CI, 0.097–0.250; Ablation Versus Anti-arrhythmic Therapy for Reducing All Hospital Episodes from Recurrent (AVATAR) protocol ablation vs. anti-arrhythmic drug therapy: primary endpoint analysis. Kaplan–Meier curves comparing AVATAR protocol ablation against drug therapy for the survival time to any hospital episode related to treatment for atrial arrhythmia. Number of remaining subjects at risk displayed at 50-day intervals. The hazard-ratio for achieving a hospital episode when comparing AVATAR protocol arm to drug therapy is 0.156 (95% CI, 0.097–0.250; Cryo-balloon atrial fibrillation (AF) ablation vs. Ablation Versus Anti-arrhythmic Therapy for Reducing All Hospital Episodes from Recurrent (AVATAR) protocol ablation: primary endpoint analysis. Kaplan–Meier curves comparing AVATAR protocol ablation against cryo-balloon AF ablation therapy for the survival time to any hospital episode related to treatment for atrial arrhythmia. Number of remaining subjects at risk displayed at 50-day intervals. The hazard ratio for achieving a hospital episode when comparing the AVATAR protocol arm against the conventional cryo-balloon ablation arm is HR 1.173 (95% CI, 0.639 to 2.154; Breakdown of endpointsAVATAR, Ablation Versus Anti-arrhythmic Therapy for Reducing All Hospital Episodes from Recurrent.
