  Fig. 2. Forest Plot depicting the Risk Ratio of developing recurrent tachyarrhythmia between the experimental (Additional Ablation) and control (Pulmonary Vein Isolation only) groups. Also illustrated is the subgroup analysis based on the strategy of additional ablations (nPVI-te, Linear Ablation, Autonomic Modulation, SM)
