1 · What the graph read from it

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.

2 · The registry

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

backgroundProcedural and clinical outcomes in patients with obesity undergoing catheter ablation for atrial fibrillation (AF) have been mixed. Clinical data in the context of pulsed field ablation (PFA) are currently limited in this patient cohort.

methodsWe conducted an observational study of consecutive patients undergoing PFA with a pentaspline catheter (Farapulse

results537 (95%) out of 564 consecutive patients underwent de novo PFA for AF between 2022 and 2025 with a recorded BMI; 326 (60.7%) were nonobese, 117 (21.8%) were obese and 94 (17.5%) morbidly obese patients. Proportion of females increased according to BMI (p = 0.003). Obesity correlated with CHA

conclusionPatients with obesity had no signal of increased risk detected with regard to procedural safety and clinical outcomes with PFA for AF compared with nonobese patients. These findings apply to a specific pentaspline PFA catheter rather than PFA technology in general.
