1 · What the graph read from 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.

2 · The registry

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

Background: Patients with atrial fibrillation (AF) and hypertrophic cardiomyopathy (HCM) commonly require repeat catheter ablation procedures for AF management. The mechanisms underlying the increased AF recurrence rates are poorly defined. Objective: We aimed to explore mapping findings and ablation outcomes among patients with HCM undergoing repeat AF ablation. Methods: In this single-center study, 45 patients with HCM underwent repeat AF ablation procedures (2015-2023). Patients were age- and sex-matched 1:1 to control patients without HCM undergoing repeat AF ablation. Details from comprehensive electroanatomic mapping were compared. Univariate and multivariate Cox regression analyses were used to evaluate prognostic factors for recurrent AF in HCM. Results: The mean age in the HCM group was 57.5 ± 13.2 and 71% were male. The most common finding at repeat ablation was pulmonary vein (PV) reconnection (86.7% in the HCM group vs 75.5% in the control group, Conclusion: PV reconnection is commonly observed in patients with HCM undergoing repeat AF ablation. Repeat AF ablation outcomes in patients with HCM were comparable to those in patients without HCM.
