Semaglutide Induces Changes in Gastric Electrical Activity in Patients With Overweight and Obesity: A Pilot Study.
Article in Journal of neurogastroenterology and motility, 2026. 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
Background/Aims: : Semaglutide is associated with gastroduodenal symptoms, such as nausea and vomiting. This pilot study used body surface gastric mapping (BSGM) to measure the effect of semaglutide on gastric function and associated symptoms. Methods: : Patients without gastrointestinal symptoms (n = 8) underwent BSGM at baseline and on 1 mg semaglutide, as per standard subcutaneous dosing. Spectral metrics included Principal Gastric Frequency, Gastric Alimetry Rhythm Index (GA-RI), body mass index-adjusted amplitude, fed:fasted amplitude ratio, and meal response ratio. Symptoms were assessed using validated questionnaires. Data were compared using paired t tests. Results: : Body mass index-adjusted amplitude showed a significant decrease on the drug ( Conclusions: : Semaglutide appears to alter gastric electrical activity on BSGM and increase early satiation, offering potential biomarkers for detecting drug effects. Further studies are needed.
