Colonic angiodysplasia: a culprit of obscure gastrointestinal bleeding in a patient with Heyde syndrome.
Article in BMJ case reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
A 77-year-old woman presented with obscure gastrointestinal bleeding requiring multiple hospitalisations and blood transfusions. The patient underwent repeated investigations over four hospital admissions across a span of two months. These included upper and lower gastrointestinal endoscopy, video capsule endoscopy as well as CT enterography, without definitive localisation or treatment of the source of bleeding. Finally, a technetium-99m-labelled red blood cell scan demonstrated a 'blush' at the proximal transverse colon on delayed imaging. Targeted colonoscopic evaluation showed a subcentimetre angiodysplastic lesion in the corresponding spot at the proximal transverse colon with slow persistent oozing. Endoscopic clips were applied with successful haemostasis. The patient recovered well without further symptom recurrence 5 months postdischarge. We review the literature on colonic angiodysplasias and discuss the diagnostic challenges in obscure gastrointestinal bleeding.
