When Bowel Preparation Worsens With Time: The Case of an Unknown Crohn's Fistula.
Article in ACG case reports journal, 2025. 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
Colonoscopy is essential for diagnosing and managing lower gastrointestinal diseases, but adequate bowel preparation is critical for success. We report the case of a 66-year-old man with quiescent Crohn's disease who experienced repeated bowel preparation failure despite adherence to intensified regimens. Imaging later revealed an ileo-sigmoid fistula diverting laxative flow, preventing proximal colonic cleansing and causing stool reaccumulation in distal segments. Internal fistulas, common in Crohn's disease, are often asymptomatic but can significantly impair preparation quality. This case highlights the need to consider anatomical abnormalities such as internal fistulas in patients with recurrent bowel preparation failure and poor visualization during colonoscopy.
