Occurrence of portal venous gas following routine endoscopy: a case report.

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
Objectives: Portal venous gas (PVG) is commonly associated with severe gastrointestinal disease, whereas benign causes related to endoscopic procedures are uncommon. We report an unusual mechanism of PVG occurring in the setting of chronic gastric outlet obstruction after carbon dioxide (CO Case presentation: A 25-year-old Asian woman presented with recurrent vomiting. She had undergone surgery for duodenal perforation six months earlier and was subsequently lost to follow-up. Her symptoms recently worsened, with significant abdominal distension and vomiting for 3 weeks. A computed tomography (CT) revealed marked gastric dilatation and fibrotic duodenal bulb stenosis. After gastric decompression, CO Conclusions: In the setting of chronic gastric outlet obstruction and prolonged gastric distension, impaired mucosal integrity together with increased intragastric pressure may predispose to abnormal CO
