Risk factors for the recurrence of atrial fibrillation after catheter ablation: a meta-analysis.
Review in The Egyptian heart journal : (EHJ) : official bulletin of the Egyptian Society of Cardiology, 2025. 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
backgroundThe rate at which atrial fibrillation (AF) patients experience a return of symptoms after catheter ablation is significant, and there are multiple risk factors involved. This research intends to perform a meta-analysis to explore the risk factors connected to the recurrence of AF in patients following catheter ablation.
methodsThe PubMed, Cochrane Library, WOS, Embase, SinoMed, CNKI, Wanfang, and VIP databases were explored for studies from January 1, 2000 to August 10, 2021, and research meeting the established inclusion requirements was chosen. Two authors separately gathered details regarding the study structure. The strength of the link between various risk factors and AF returning after CA was evaluated using odds ratios. All statistical evaluations were conducted with RevMan5.3 software.
resultsIn total, 44 articles and 62,674 patients were included. The OR for AF recurrence in patients with diabetes was 2.04 compared with the reference group (95% CI 1.51-2.76, p < 0.00001); that of lower left ventricular ejection fraction was 1.38 (95% CI 1.25-1.52, p < 0.00001); that of female was 1.34 (95% CI 1.18-1.52, p < 0.00001); that of increased age was 1.03 (95% CI 1.02-1.04, p < 0.00001); that of persistent AF was 1.72 (95% CI 1.58-1.87, p < 0.00001); that of AF duration over 2 years was 1.17 (95% CI 1.08-1.26, p < 0.00001); that of increased left atrial diameter (LAD) was 1.12 (95% CI 1.08-1.17, p < 0.00001); that of larger left atrial volume index (LAVi) was 1.02 (95% CI 1.01-1.03, p < 0.00001); that of higher hs-CRP was 1.19 (95% CI 1.04-1.36, p = 0.04); that of early recurrence (ER) was 3.22 (95% CI 2.74-3.77, p < 0.00001); and that of long ablation duration was 1.00 (95% CI 0.98-1.02, p = 0.72). Heterogeneity and slight publication bias were observed for each factor.
conclusionsEvidence indicates that diabetes, low left ventricular ejection fraction, being female, older age, longer duration of atrial fibrillation, elevated high-sensitivity C-reactive protein levels, large left atrial dimension, large left atrial volume index, persistent atrial fibrillation, and exercise rehabilitation are factors that increase the chances of getting atrial fibrillation again after catheter ablation. However, the length of the ablation procedure does not relate to the recurrence of AF.
