1 · What the graph read from it

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.

2 · The registry

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

Introduction: Intestinal endometriosis is a benign condition characterized by the presence of endometrial tissue within the bowel wall, often mimicking colorectal malignancy. Its coexistence with ulcerative colitis (UC) is rare and can complicate the diagnosis. Case Presentation: A 35-year-old woman with long-standing UC presented with severe diarrhea and rectal bleeding. Colonoscopy revealed severe disease activity with multiple deep ulcerations and a newly developed stricture in the sigmoid colon. Pathological examinations, including bite-on-bite biopsies, showed no evidence of malignancy. However, colitis-associated neoplasia (CAN) could not be completely ruled out because such lesions may primarily involve the deep layers of the colonic wall. Given the severity of disease and concern for possible CAN, a total colectomy was performed. Histopathological and immunohistochemical analysis of the resected specimen ultimately identified intestinal endometriosis as the cause of the stricture. Conclusion: This case underscores the importance of considering intestinal endometriosis in women with UC who develop unexplained colonic strictures, particularly when malignancy cannot be confirmed.
