Clinical Vulnerability Refines Rhythm-Related Outcomes in Older Patients Undergoing Pulmonary Vein Isolation for Atrial Fibrillation: An Observational Cohort Study.
Article in Journal of arrhythmia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Chronological age is often considered when selecting patients for atrial fibrillation (AF) ablation, but age alone may not identify which older patients are most likely to require recurrent rhythm-related care after pulmonary vein isolation (PVI). Methods: We conducted a single-center observational study of consecutive patients undergoing PVI. The principal registry cohort assessed the same-center recurrence-related rhythm-intervention endpoint, defined as the first post-index repeat PVI or electrical cardioversion. A nested active 2022 cohort assessed broader actively ascertained recurrence. Age was analyzed as < 50, 50-74, and ≥ 75. An exploratory elderly vulnerability score assigned one point each for documented persistent AF, heart failure, chronic kidney disease, and valve disease/surgery. Results: The registry cohort included 2559 patients and 580 same-center rhythm-intervention events. Event rates increased across age groups: 14.2% in patients aged < 50, 20.8% in those aged 50-74, and 29.8% in those aged ≥ 75. Age ≥ 75 was independently associated with higher risk versus age 50-74 in adjusted registry Cox analysis, HR: 1.35, 95% CI: 1.12-1.64, Conclusion: Age ≥ 75 was associated with a higher rate of same-center recurrence-related rhythm interventions after PVI, but the risk varied substantially. Clinical vulnerability, not chronological age alone, may better inform counseling and selection of older patients.
