Post-ablation P wave characteristics correlate with recurrent atrial fibrillation in the ABCD-AF cohort.

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
purposeAtrial fibrillation (AF) ablation is a common procedure to reduce cardiovascular morbidity but is limited by recurrence. The objective of this study was to determine if post-ablation acute surface P wave morphology and other electrocardiographic parameters correlate with AF recurrence.
methodsThe Avoiding Bladder Catheters During AF ablation (ABCD-AF) trial was a randomized, prospective trial in 160 subjects undergoing AF ablation. The present study examined correlation between AF recurrence in follow-up and acute post-ablation electrocardiographic P wave parameters.
resultsMedian follow-up was 255 (188, 306) days. The ABCD-AF cohort had a mean age of 62.7 ± 12.8 with 32.1% being females. Rate of recurrent AF was 35.8%, with a median time to AF of 135 (109, 182) days. There was no baseline demographic associated with AF recurrence. There was more AF recurrence in those with longer follow-up (p = 0.001). Lead 2 PR interval, lead 2 P wave duration/PR (Pdur/PR), lead V1 PR interval, and lead V1 Pdur/PR were all significantly associated with recurrent AF (p = 0.03, 0.02, 0.01, 0.01). Longer PR and shorter Pdur/PR predicted AF recurrence. In a multivariable model, lead V1 Pdur/PR provided the best predictor of AF recurrence, with an odds ratio of 0.018 (p = 0.016) per standard deviation change.
conclusionsShorter P wave duration combined with longer AV node delay, as measured by proportion of the PR that the P wave occupies, was the best predictor of AF recurrence post-ablation.
