P-Wave Parameter Changes After Pulsed-Field Ablation, Cryoballoon Ablation and Radiofrequency Ablation for Paroxysmal Atrial Fibrillation: An Observational Cohort Study.
Article in Journal of arrhythmia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Pulmonary vein isolation (PVI) is central to controlling paroxysmal atrial fibrillation (AF). Pulsed-field ablation (PFA) offers a non-thermal alternative to conventional thermal techniques. The study compares changes in P-wave parameters following PFA, radiofrequency ablation (RF), and cryoballoon ablation (Cryo). Methods: We retrospectively analysed 283 patients undergoing first-time PVI (RF 101, Cryo 125, PFA 57). Digital electrocardiograms (ECGs) were evaluated for P-wave duration (PWD), voltage (PWV), dispersion (PWDisp), and terminal force in lead V1 (PTFV1) before and immediately after ablation. AF recurrence was assessed at 12 months. Analyses were adjusted for left atrial volume index (LAVI) and post-procedural anti-arrhythmic drug (AAD) use. Results: At 12 months, 215 patients (76%) remained free of AF (RF 76%, Cryo 74%, PFA 79%; Conclusions: PFA, RF, and Cryo produce similar acute ECG changes. Post-procedural PWD was the strongest predictor of AF recurrence, independent of atrial size and AAD use.
