Association between Body Mass Index and Left Ventricular Ejection Fraction in Obese Patients with Atrial Fibrillation Referred for Catheter Ablation.
Article in Frontiers in nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Atrial fibrillation (AF) is one of the most common arrhythmias associated with obesity and metabolic disorders. However, little is known about the association between body mass index (BMI) and left atrial size and left ventricular ejection fraction (LVEF) in AF patients referred for catheter ablation. Methods: We retrospectively obtained a dataset ( Results: Correlation analysis displayed that BMI was negatively associated with LVEF, but it had no correlation with left atrial volume (LAV)/body surface area (BSA). When evaluating BMI as an independent variable, our linear regression analysis for adjusted coefficient of LVEF [correlation coefficient = -0.46, 95% CI: (-0.78, -0.15), Conclusion: We observed that BMI had a significantly negative correlation with LVEF but not with LAVmax/BSA or LAVmin/BSA in the obese patients with AF referred for catheter ablation. This suggests that obesity may be associated with an increased risk of impaired cardiac contractile function in these patients.
