Catheter Ablation Versus Medical Therapy for Atrial Fibrillation in Patients with Heart failure: A Meta-Analysis of Randomized Controlled Trials.
Synthesis in Anatolian journal of cardiology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 2 of them syntheses that pooled it.
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
backgroundThe optimal treatments for atrial fibrillation in heart failure patients are controversial. The present study compared the efficacy of catheter ablation and medical therapy in patients with atrial fibrillation and heart failure.
methodsPubmed, Embase, Cochrane Library, and Web of Science were searched until January 15, 2022. Randomized controlled trials comparing catheter ablation for atrial fibrillation with medical therapy in patients with atrial fibrillation and heart failure were enrolled. Primary outcome was all-cause mortality. Secondary outcomes included the heart failure hospitalization and the change in left ventricular ejection fraction, 6-minute walk test distance, peak oxygen consumption, and Minnesota Living with Heart Failure questionnaire score.
resultsTotally 8 randomized controlled trials involving 1693 patients were included. Compared with medical therapy, catheter ablation significantly reduced all-cause mortality (risk ratios=0.60, 95% Cl: 0.45 to 0.80, P < .001) and hospitalization due to heart failure (risk ratios=0.58, 95% Cl: 0.46 to 0.73, P < .001), improved left ventricular ejection fraction (mean difference=5.25%, 95% CI: 2.78% to 7.71%, P < .001), improved the performance of 6-minute walk test (mean difference=28.83 m, 95% CI: 8.61 to 49.05 m, P=.005), increased peak oxygen consumption (mean difference=3.11 mL/kg/min, 95% CI: 1.04 to 5.18 mL/kg/min, P=.003), and reduced Minnesota Living with Heart Failure score (mean difference=-8.45, 95% CI: -16.28 to -0.62, P=.03).
conclusionIn heart failure patients with atrial fibrillation, catheter ablation provides more benefits over medical therapy in the important clinical outcomes, exercise capacity, and quality of life.
