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 Aim: There is limited literature regarding endoscopic removal of gastrointestinal stromal tumors (GISTs) located in the duodenum. We present successful endoscopic submucosal dissection and exposed full-thickness resection (FTR) of an incidentally discovered duodenal GIST in an asymptomatic 65-year-old man. Methods: The lesion was 1.4 cm and well-defined, primarily located in the submucosal layer of the posterior D2 duodenal wall and the level of the major papilla around 2 cm distal to the ampulla. Transverse mucosotomy was made followed by submucosal dissection. An IT2 knife with a protected tip was used for the majority of resection to preserve the lesion's capsular layer. Methodical dissection was performed until the lesion was removed en bloc. Endoscopic suturing closed the FTR defect with a single running suture. An exposed aspect of the medial mucosal resection site was reinforced with an additional interrupted suture. Results: Postclosure contrast duodenogram was negative for leak. The patient was monitored for 36 hours inpatient without adverse events. Final pathology confirmed complete en bloc resection of a low-grade GIST with a preserved capsule. Conclusion: Endoscopic submucosal dissection/exposed FTR can be an effective, minimally invasive method of resecting duodenal GISTs. In addition, endoscopic suturing is a viable method of resection defect closure in the duodenum.
