Safety and efficacy of catheter ablation in atrial fibrillation patients with left ventricular dysfunction.
Article in Clinical cardiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
backgroundCatheter ablation (CA) for atrial fibrillation (AF) in heart failure (HF) patients reduced the mortality but may increase complications and raise the safety concern. HYPOTHESIS: CA for AF in HF patients may not increase the complications vs medical treatment, and it may reduce hospitalizations and mortality and improve heart function.
methodsThree groups of AF patients were included in the study: 120 congestive HF for their first CA (AFHF-CA), 150 congestive HF who were undergoing medical therapy (AFHF-Med), and 150 patients with normal left ventricular (LV) ejection fraction (LVEF) (AF-CA).
resultsAfter 30 ± 6 months of follow up, 45.8% of patients in the AFHF-CA and 61.3% of patients in the AF-CA groups maintained sinus rhythm (SR) in comparison with 2.7% in AFHF-Med (P < .01). Hospitalization for HF was significantly lower in AFHF-CA than in AFHF-Med groups (P < .01). Death occurred in 7.5% of patients in the AFHF-CA group, which was lower than 18% in the AFHF-Med group (P < .01). Significant improvements in heart function were shown in the AFHF-CA group compared to the AFHF-Med group, including LVEF (P < .01), LV end-diastolic diameter (P < .01), and New York Heart Association classification (P < .01), as well as the left atrial diameter (P < .01). AFHF-CA patients required additional ablation more often (P < .05). CA had a better prognosis in paroxysmal AF and tachycardia-related diseases.
conclusionCA for AF reduced hospitalizations and mortality and improved heart function, vs medical treatment, and was as safe as CA in those with normal heart function.
