Collagenous Colitis in a Young Adult: A Case Report.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Collagenous colitis is a subtype of microscopic colitis characterized by chronic watery diarrhea, normal-appearing colonic mucosa on endoscopy, and a thickened subepithelial collagen band on histological examination. Although it is often observed in middle-aged women, increasing recognition of this condition has expanded its epidemiological spectrum. We describe the case of a 21-year-old woman presenting with persistent watery diarrhea and weight loss. Extensive evaluation, including endoscopy with biopsies, confirmed collagenous colitis. This case highlights diagnostic and therapeutic considerations in young patients with chronic diarrhea. Although colonoscopy findings may be normal, further mucosal biopsies are essential for diagnosis. Budesonide remains the first-line treatment and achieves high remission rates. Collagenous colitis should be considered in the differential diagnosis of chronic watery diarrhea, even in young adults. Furthermore, early biopsy and appropriate therapy are crucial for symptom control and improved quality of life.
