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 AND
aimsGLP-1 receptor agonists (GLP-1RAs) promote significant weight loss, but their impact on muscle mass, strength, and quality in metabolic dysfunction-associated steatotic liver disease (MASLD), a condition prone to muscle impairment, remains uncertain.
methodsWe conducted a systematic review of MEDLINE/PubMed, Embase, and the Cochrane Library up to 2 December 2025. Interventional and observational studies assessing GLP-1RA therapy and muscle-related outcomes in adults with MASLD were included. Muscle mass was assessed by computed tomography or magnetic resonance imaging, dual-energy X-ray absorptiometry, or bioelectrical impedance analysis; lean mass and fat-free mass were considered proxies. Muscle strength was evaluated using handgrip strength (HGS) or sit-to-stand (STS) tests. Muscle quality was assessed by imaging-based quantification of intramuscular fat infiltration (myosteatosis) or functionally based on performance relative to muscle mass. Results were synthesised narratively.
resultsTwelve studies were included (n = 810). Eleven assessed muscle mass (n = 785) across different GLP-1RA regimens and treatment durations (12-52 weeks). Findings suggested relative preservation of muscle mass, with modest reductions generally proportional to overall weight loss. Muscle strength was evaluated in three studies (n = 477), with no evidence of deterioration in HGS or STS performance despite meaningful weight loss. Muscle quality was assessed in four studies (n = 139) using imaging or functional metrics, with results suggesting preserved or improved muscle quality. Evidence was limited by small sample sizes and heterogeneous assessment methods.
conclusionCurrent evidence suggests that GLP-1RA therapy is not associated with clinically meaningful loss of muscle mass or strength in adults with MASLD, with early data indicating possible improvements in muscle quality.
