Clinical Characteristics and Outcomes of Catheter Ablation in Young Patients With Atrial Fibrillation.
Article in Clinical cardiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundData concerning young patients with atrial fibrillation (AF) are currently limited. HYPOTHESIS: This study aimed to assess the clinical characteristics and risk factors for AF recurrence in young patients following catheter ablation (CA).
methodsAll AF patients aged ≤ 45 years who underwent CA were identified from the China Atrial Fibrillation Center database between September 2018 and September 2023. Baseline clinical characteristics, procedural details, and follow-up outcomes were compared between the paroxysmal and non-paroxysmal cohorts.
resultsA total of 6,531 young patients with AF were included in the final analysis, with an average age of 37.7 ± 5.5 years, 77.1% were male, and 65.2% with paroxysmal AF. The primary comorbidities were hypertension (16.2%), heart failure (8.4%), valvular heart disease (3.5%), diabetes mellitus (3.2%), peripheral arterial disease (2.8%), stroke/transient ischemic attack (2.5%), and cardiomyopathy (2.2%). Following CA, the recurrence rate of AF post-CA was 14.4% across the entire cohort, with a lower recurrence rate in the paroxysmal AF group compared to the non-paroxysmal AF group (10.6% vs. 19.7%, p < 0.001). Non-paroxysmal AF (HR 2.34, 95% CI 1.62 to 3.36, p < 0.001) and hypertension (HR 1.69, 95% CI 1.09 to 2.63, p = 0.019) were identified as independent predictors for AF recurrence.
conclusionYoung AF patients who undergo CA exhibit a low recurrence rate and a notable improvement in symptoms post-CA. Non-paroxysmal AF and hypertension emerge as primary contributors to AF recurrence following CA in this population.
