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
backgroundTo date, data about pulsed field ablation (PFA) for ventricular arrhythmias are limited, and cardiac magnetic resonance (CMR) characteristics of acute and chronic PFA lesions in the ventricles have not been described. This study sought to examine feasibility and efficacy of premature ventricular complex (PVC) ablation using focal PFA, as well as assess acute and chronic lesion characteristics using CMR.
methodsThis was a prospective, single-arm study performed at two centers in China. Consecutive patients with frequent, symptomatic PVCs were consented and recruited. All procedures were performed using a comprehensive cardiac PFA system. PVC burden evaluation and CMR were performed before the procedure, within 3 days, and at approximately 6 months post-procedure.
resultsTwelve patients (mean age 54 ± 14 years, 41.7% female) were included and underwent ablation. The PVCs originated in the right ventricular outflow tract in seven (58.3%) patients, the left ventricular outflow tract in three (25%) patients, the left anterior papillary muscle in one (8.3%) patient and para-Hisian septum in one (8.3%) patient, respectively. Nine (75%) patients had complete elimination of PVCs after PFA. The PFA lesions were visualized and quantified by CMR in 6 out of 12 patients. The median volume evaluated by acute late gadolinium enhancement was 726 (430, 1544) mm
conclusionPFA showed favorable efficacy and safety in patients with frequent PVCs. CMR imaging allows clear visualization and quantitative analysis of PFA lesions, which showed a significant size regression from acute to chronic period.
