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 Aims: It has been estimated that nearly half of patients with gastroparesis use opioids long term, are unable to cease or wean opioid use, and continue to endorse debilitating symptoms. The aim of this study was to evaluate outcomes of gastric peroral endoscopic myotomy (G-POEM) as compassionate treatment in patients with gastroparesis who are unable to discontinue long-term opioid use. Methods: This was a multicenter retrospective analysis of prospective databases containing patients with gastroparesis taking opioids who underwent G-POEM between January 2021 and November 2024. Functional luminal imaging probe (FLIP) pyloric measurements were obtained pre- and post-G-POEM at follow-up. Clinical response to G-POEM was defined as improvement of ≥1 point on the Gastroparesis Cardinal Symptom Index. Results: Thirty-eight patients with gastroparesis on opioids with a median follow-up of 6 months (range, 3-18 months) underwent G-POEM during the study period. Technical success was 100%. Clinical success was achieved in 60.5% (23/38) of the patients. There were no differences in demographics, symptom duration, etiology of gastroparesis, baseline Gastroparesis Cardinal Symptom Index score, gastric-emptying scintigraphy or daily morphine milligram equivalent between responders and nonresponders. When compared with nonresponders, patients who responded to G-POEM had a significantly lower FLIP baseline pyloric diameter (13.2 [standard deviation (SD) 3.4 mm Conclusions: This study suggests that G-POEM could be considered as a safe and effective compassionate treatment in select patients with gastroparesis who are taking opioids long term, particularly those with lower pyloric compliance on physiologic testing. Future studies are needed to corroborate these preliminary findings.
