Forest plot of the study-specific RRs for AF recurrence after ablation for every 10% weight loss. Study-specific estimates obtained by the method of Greenland and Longnecker assuming a linear relationship of the RRs to the referent in a random-effects model. Referents for weight loss were the individuals reporting no weight loss or stable weight within the specific study. The diamond indicates the pooled estimate. Red boxes are relative to study size, and the black vertical lines indicate 95% CIs around the effect size estimate
