Evaluating the Precision of Intra-Spline Bipolar Potentials With Pentaspline Pulsed Field Ablation Catheter.
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
Background: Conventional cross-spline bipolar electrograms (CSBEs) with the pentaspline pulsed field ablation (PFA) catheter suffer from far-field interference. Intra-spline bipolar electrograms (ISBEs) can provide more localized data. We evaluated ISBE efficacy in enhancing mapping precision. Methods: In 20 AF patients post-PVI, left atrial maps were constructed. We compared 13 533 CSBEs and 8097 ISBEs for voltage and peak frequency, excluding noise/scar potentials. Results: ISBEs yielded significantly higher peak frequencies (median: 236 vs. 185 Hz, Conclusions: ISBEs enhance mapping precision by reducing far-field interference and providing localized electrophysiological data during pentaspline PFA.
