Figure 3,4: Forest plots of the primary pooled analysis demonstrating the effect of high-power short-duration RFA vs. conventional RFA in patients with atrial fibrillation. Data are events in each group and weighted odds ratios. The horizontal line is the 95% CI. The diamond shape is the pooled mean difference of all studies. CI: confidence interval; RFA: radiofrequency ablation, PVR: pulmonary vein reconnection.
