Impact of Frailty on Recurrence After Catheter Ablation for Atrial Fibrillation: A Systematic Review and Meta-analysis.

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
Frailty is an increasingly recognized marker of biological vulnerability in patients with atrial fibrillation (AF). Although catheter ablation (CA) is an established rhythm-control strategy, atrial tachyarrhythmia (AT) recurrence remains common, particularly in patients with advanced age and comorbidity burden. The impact of frailty on post-ablation recurrence has not been systematically quantified. We systematically searched MEDLINE, EMBASE, and the Cochrane Library for studies evaluating the association between frailty and AT recurrence following CA for AF. Eligible studies compared frail and non-frail adults undergoing CA and reported post-procedural recurrence. Pooled risk ratios (RRs) with 95% confidence intervals (CIs) were calculated using a random-effects model. Four studies totaling 1096 patients were included, of whom 266 (24.3%) were frail. Across the included studies, the mean age of participants ranged from approximately 61 to 76 years. Frailty was associated with a significantly higher risk of AT recurrence after CA compared with non-frailty (RR, 1.57; 95% CI, 1.26-1.94;
