Renal function after repeat catheter ablation for long-standing persistent atrial fibrillation : Low CHA2DS2-VASc score and sinus rhythm predict improved renal function.

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
backgroundRenal impairment and atrial fibrillation (AF) often coexist. Catheter ablation is an effective way to reduce the burden of AF and improve symptoms; however, little is known about the relationship between renal function and AF and its role in the progression of AF for patients undergoing repeat catheter ablation.
methodsIn all, 171 patients with long-standing persistent AF ablation were enrolled in the study. The patients were divided into two groups according to their delta estimated glomerular filtration rate (eGFR) values, which was defined as the eGFR before the repeat procedure minus the eGFR before the initial procedure. Patients with decreasing eGFR (delta eGFR < 0) were categorized as group I, while individuals with no change or increasing eGFR (delta eGFR≥ 0) were categorized as group II. eGFR was estimated at baseline and at the 12-month and 24-month follow-up visits.
resultsAfter a mean follow-up of 31.4 ± 13.2 months, group I had a significantly higher arrhythmia recurrence rate than group II (71.2 vs. 49.2 %, p < 0.001). On multivariable analyses, eGFR changes after the repeat procedure were associated with arrhythmia recurrence, hypertrophic cardiomyopathy, and CHA2DS2-VASc score. Patients with arrhythmia recurrence and those with a CHA2DS2-VASc score of ≥ 3 were more likely to show an eGFR decline at follow-up.
conclusionPatients with long-standing persistent AF, with a failed initial ablation procedure and undergoing a repeat ablation procedure, appear to have a higher risk of arrhythmia recurrence. During the follow-up period, patients without arrhythmia recurrence and those with a CHA2DS2-VASc score of < 3 show improved renal function.
