Fig. 2From: Association between weight loss and outcomes in patients undergoing atrial fibrillation ablation: a systematic review and dose–response meta-analysisForest plot of the study of weight loss and AF recurrence after AF ablation in a random-effects model, stratified by study design. 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 or blue boxes are relative to study size, and the black vertical lines indicate 95% CIs around the effect size estimateBack to article page
