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: Obesity is a major risk factor for atrial fibrillation (AF). Individuals with obesity can be further classified into metabolically unhealthy obesity (MUO) or healthy obesity (MHO) groups based on the metabolic health subtype. The influence of these phenotypes and overweight status on AF ablation outcomes remains unclear. Objective: This study aimed to examine the recurrence of paroxysmal AF (PAF) after ablation in patients across distinct obesity phenotypes. Methods: From January 2019 to November 2023, 599 patients with drug-refractory PAF undergoing a first ablation were retrospectively analyzed. Based on the World Health Organization-defined body mass index thresholds for Asians regarding overweight (23-25 kg/m Results: The mean age of the patients was 60.7 ± 11.7 years, and 64.1% were men. Compared with the normal-weight patients, AF recurrence was higher in the MUOW (19.8%), MHO (18.0%), and MUO (14.9%) groups after an average follow-up of 534 days, with respective hazard ratios (HRs) of 3.240 (p = 0.003), 2.973 (p = 0.013), and 2.182 (p = 0.033) after adjusting for chronic kidney disease. MHOW (14.9%; HR 2.593, p = 0.053) showed a non-significant trend toward a higher risk. Complete pulmonary vein isolation was achieved in all patients. Conclusions: Overweight and obesity, regardless of metabolic status, were associated with a significantly higher risk of AF recurrence after ablation compared to normal-weight, underscoring the importance of weight management in PAF.
