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
Securing large duodenal defects after endoscopic full-thickness resection (EFTR) is challenging because of anatomic constraints. This case report describes an innovative closure technique using a modified long transparent cap in a 48-year-old man who underwent EFTR for a 2.0 × 2.5-cm duodenal bulb gastrointestinal stromal tumor, resulting in a 1.5 × 2.5-cm full-thickness defect. Titanium clips closure failed. A long ligation device cap (inner diameter 0.9 cm, outer diameter 1.1 cm) was used to suction opposing mucosal edges, enabling precise titanium clip placement under endoscopic guidance. The cap-assisted technique achieved secure defect closure. Margin-negative resection was confirmed, and the patient recovered without adverse events. To our knowledge, we report the first use of a long transparent cap that helped successfully close a large duodenal defect following EFTR, offering a practical alternative in anatomically challenging locations or resource-limited settings.
