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
introductionCardioneural ablation (CNA) and fluoroless ablation (FA) are emerging procedures and movements in contemporary in electrophysiology. Ablation of ganglionated plexus (GP) inputs in the atrium has been successfully targeted as a treatment for symptomatic bradyarrhythmias due to increased parasympathetic tone. As most of these patients are young, avoidance of ionizing radiation is of critical importance to limit potential long term deleterious effects. With widespread use of 3D electroanatomic mapping systems and advanced intracardiac echo (ICE) imaging, fluoroless ablation has become more widely adopted. However, fluoroless CNA has not been widely performed. The objective of this study is to demonstrate that CNA can be done safely and effectively without fluoroscopy.
methodsAt a single-center, consecutive patients undergoing CNA with a fluoroless approach are described. GP mapping and ablation were performed in both atria. From the right atrium (RA), the right atrium-superior vena cava (RA-SVC GP), the posteromedial ganglionated plexus (PMLGP), which can be accessed from the right atrium-coronary sinus ostium, and the Vein of Marshall GP (VOM-GP) were evaluated. From the left atrium (LA), the superior left atrial ganglionated plexus (LSGP), the left inferior ganglionated plexus (LIGP), the right anterior ganglionated plexus (RAGP), and the right inferior ganglionated plexus (RIGP) were targeted.
resultsOver the study period, beginning on January 31, 2021, 30 consecutive subjects (15 females/15 males) aged 42.9 ± 13.6 years underwent GP ablation. The average subject had 9.5 (± 9.2) episodes of syncope prior to ablation. The average CHADS
conclusionIn comparison to the traditional CNA with fluoroscopy, this proof of concept study reveals fluoroless GP ablation can be performed safely. In addition, the durability and success rate are comparable to other studies of CNA. Given the young age of the cohort and the longitudinal risks of ionizing radiation, fluoroless CNA is a feasible procedure for this patient population.
