Instant termination as a novel indicator for prognosis of persistent atrial fibrillation during cryoballoon ablation: a propensity score-matched 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
Background: Instant atrial fibrillation termination (AFT) during radiofrequency ablation has been suggested as a predictor of prognosis in persistent atrial fibrillation (AF). However, its role in cryoballoon ablation remains unclear. This study investigated the association between AFT and recurrent atrial tachyarrhythmia in patients with persistent AF undergoing cryoballoon ablation. Methods: Patients with non-valvular, drug-resistant, persistent AF who underwent cryoballoon ablation between January 2021 and June 2023 were included and categorized based on the presence or absence of AFT. Propensity score matching (PSM) was applied to eliminate covariate imbalances. Baseline characteristics, procedural details, and clinical outcomes were compared between the groups. Results: A total of 189 patients [65.0 (59.0-71.0) years] were included. Among them, 41 experienced instant AFT, while 148 remained in AF rhythm. The baseline conditions were similar, except that patients with AFT presented significantly lower left atrial diameter (LAD). During a follow-up of 16.0 [9.1-26.9] months, the recurrence rates of arrhythmias were significantly lower in the AFT group (log-rank Conclusion: Instant AFT during cryoballoon ablation is associated with a reduced risk of arrhythmic recurrence in patients with persistent AF.
