A case report of an unexpected colonic polyp: cavernous hemangioma.
Article in Annals of coloproctology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Cavernous hemangiomas of the colon are rare, benign vascular lesions, and the site most commonly affected is the rectosigmoid junction. Surgical treatment is recommended for large diffuse lesions but in the presence of pedunculated lesions, endoscopic resection should be preferred if possible. We report a case of a 65-year-old man referred for colonoscopy after positive fecal occult blood, that revealed at the level of the sigmoid colon, a wide base pedunculated polyp (35 mm) occupying more than half of the lumen, with the covering mucosa with a vinous appearance. In order to remove the lesion, a detachable snare was placed and polypectomy was performed. During the procedure, the detachable snare was cut with active bleeding, controlled after clip placement and diluted adrenaline injection. Afterwards, histology revealed a polypoid lesion with a hyperplastic mucosa and submucosal plane expanded by numerous thick-walled vessels in the context of a cavernous colonic hemangioma.
