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 study aims: It is currently unclear whether obstruction location affects clinical and procedure outcomes after endoscopic ultrasonography-guided gastroenterostomy (EUS-GE) with a lumen-apposing metal stent (LAMS) in patients with malignant gastric outlet obstruction (GOO). Therefore, we compared clinical outcomes of EUS-GE for malignant GOO located in the stomach with obstruction located in the duodenum. Patients and methods: In this nationwide, multicenter, retrospective study, we included consecutive patients who underwent EUS-GE as palliative treatment for malignant GOO. Main outcomes were clinical success, serious adverse events (SAEs) recurrence of obstructive symptoms, and LAMS dysfunction. Results: Between 2018 and 2023, 298 patients underwent EUS-GE. Clinical success was achieved in 73 of 82 patients with a gastric obstruction (94%) and in 174 of 216 patients with a duodenal obstruction (87%). No association was found between location of obstruction and clinical success (odds ratio [OR] 2.62, 95% confidence interval [CI] 0.91 to 7.52, Conclusions: In this study, EUS-GE in patients with a gastric obstruction had comparable technical and clinical efficacy and a similar safety profile to EUS-GE for duodenal obstruction. However, gastric obstruction was associated with recurrent symptoms of obstruction unrelated to LAMS dysfunction.
