A Case Report of Mechanical Intestinal Obstruction Caused by Delayed Heterotopic Ossification of Postoperative Incision.
Article in Clinical case reports, 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
Heterotopic ossification (HO) refers to the abnormal formation of mature lamellar bone within soft tissues where bone is not typically present, such as muscles, tendons, ligaments, and joint capsules. While commonly associated with trauma, spinal cord injury, or orthopedic procedures, abdominal incisional heterotopic ossification (AIHO) is exceedingly rare. Its pathogenesis may be closely related to local trauma, inflammatory responses, and genetic predisposition. AIHO typically occurs between 3 months and 5 years postoperatively, with an estimated incidence of 0.3%-1.2% among all HO cases. Ossified masses can compress or mechanically tether the intestines, resulting in bowel obstruction. Herein, we report a rare case of AIHO causing mechanical intestinal obstruction 20 years after a hysterectomy. The diagnosis was confirmed by abdominal computed tomography, and the patient underwent successful surgical resection. We also review the literature and summarize strategies for the management and prevention of this complication.
