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: Left atrial (LA) enlargement is a widely recognized factor that increases the risk of ablation failure in patients with atrial fibrillation (AF). This retrospective, observational study aimed to assess the influence of vein of Marshall (VOM) ethanol infusion (VOM-EI) on persistent atrial fibrillation (PsAF) ablation among patients with severe LA enlargement. Methods: In this research, 178 patients underwent the VOM-EI followed by the radiofrequency (RF) ablation procedure, which was based on circumferential pulmonary vein antrum (CPVA) ablation and linear ablation of the roof of the LA and the mitral isthmus (MI). In comparison, 83 patients only underwent the RF ablation procedure. Results: In the VOM + RF ablation group, the duration of left CPVA ablation was shorter compared to the RF ablation group (20.3 ± 8.7 minutes vs. 27.1 ± 8.1 minutes, Conclusion: The VOM-EI facilitated the left CPVA and the MI ablation and improved the ablation outcomes in patients with severe LA enlargement for treating PsAF.
