Safety and Efficacy of GLP-1 Agonists in a Cohort of Patients with Fontan Circulation.
Article in Pediatric cardiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
There are a growing number of adult patients palliated to a Fontan circulation. As these patients age, many develop symptomatic heart failure (d'Udekem et al in Circulation 130:S32-S38, 2014) that is exacerbated by acquired comorbidities such as obesity and hypertension. Increased body mass index (BMI) and adiposity have been associated with worse hemodynamics and clinical outcomes in these patients (Yogeswaran et al in J Am Hear Assoc: Cardiovasc Cerebrovasc Dis 12:e026732, 2023). Recently, glucagon-like peptide-1 (GLP-1) agonists, originally developed to treat diabetes mellitus, received FDA approval for weight loss and have been shown to reduce the risk of cardiovascular events in the general population (Vilsbøll et al in BMJ 344:d7771, 2012). There are limited data on these medications in patients with a Fontan circulation. We conducted a retrospective review of adults with Fontan circulation followed in our adult congenital heart disease (ACHD) clinic between 2009 and 2023 and identified 8 patients prescribed GLP-1 agonists. We found that GLP-1 agonists were well-tolerated and led to modest reduction in weight and blood pressure. Further study of the use of these medications in this population is warranted.
