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
backgroundPulse field ablation (PFA) is a novel ablation technology with efficacy and safety, potentially making it a preferred ablation technology for persistent atrial fibrillation (AF). There is no optimal procedural workflow established to optimize efficacy, limiting the number of PFA applications and risks of the procedure. Due to the importance of optimal catheter-tissue contact for effective pulse field ablation, a workflow combining superior left atrial intracardiac echo (ICE) imaging and electroanatomic mapping (EAM) is an attractive strategy for PFA of persistent AF.
methodsA detailed procedural workflow was developed for fluoroscopy-free PFA using a pentaspline ablation catheter supported by left atrial ICE and EAM, and a case series of its execution in 30 consecutive patients with persistent AF is presented. All patients underwent pulmonary vein and posterior wall isolation as the index procedure, followed by additional ablation targeting non-pulmonary vein triggers and other inducible atrial arrhythmias.
resultsLeft atrial ICE imaging and EAM guided procedure resulted in successful isolation of the pulmonary veins and posterior wall in all patients, with additional ablation of spontaneous arrhythmias or non-pulmonary triggers if induced. There were no major complications of the procedure. Average procedure times and short-term efficacy were comparable with reported PFA outcomes using traditional imaging techniques.
conclusionsFluoroscopy-free PFA guided by left-sided ICE for persistent AF can be performed with superior catheter-tissue contact imaging in a safe manner with a comparable procedural time and short-term efficacy as reported with the use of other imaging modalities.
