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
aimsSubstrate modification, including left atrial posterior wall isolation (LAPWI), may be performed in AF patients undergoing catheter ablation. Pulsed field ablation (PFA) may protect adjacent structures like the esophagus. However, data on esophageal safety following PFA-guided LAPWI are limited. The aim is to evaluate esophageal safety during post-procedural esophagogastroduodenoscopy (EGD) and follow-up after PFA-guided LAPWI in patients with AF. METHODS AND
resultsThis prospective observational study included consecutive AF patients who underwent PFA-guided LAPWI and post-procedural EGD (the day after PFA), with follow-up for long-term safety. In total, 106 consecutive patients (94% persistent AF, 66 ± 14 years, 70% male, 2 ± 1 prior ablation procedures) were included. The total median procedure time was 78 [interquartile range (IQR): 49-111] min, and a mean of 50 ± 19 and 21 ± 9 PFA applications were delivered per patient and on the LAPW, respectively. One suspected transient ischaemic attack and three minor complications occurred. No thermal, ablation-related esophageal lesions were observed in any patient during EGD. Non-ablation-related incidental gastrointestinal findings were detected in 70% of patients. During a median follow-up of 606 days [IQR: 212-922], no additional esophageal adverse events were reported. Atrial arrhythmia recurrences occurred in 34% (36/106) patients (including antiarrhythmic drugs). Left atrial posterior wall isolation durability was 78% (11/14).
conclusionIn this real-world cohort, PFA-guided LAPWI was safe for the esophagus, with no thermal injury observed in post-procedural endoscopy. These results further support PFA as a promising technology for AF ablation with a favourable esophageal safety profile. The role of post-ablation proton pump inhibitors in a population where incidental gastrointestinal findings were common needs further exploration.
