When the colon takes a hit: a rare case of acute colonic intramural hematoma after blunt abdominal trauma.

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
Acute colonic intramural hematomas are rare but clinically significant. They are associated with anticoagulation use, coagulopathies, and trauma. We report a case of a 20-year-old male who was referred to the trauma hospital from an outside institution with right lower quadrant pain and a palpable mass the day of a motor vehicle accident. Computed tomography and magnetic resonance imaging showed an intramural colonic hematoma (measuring 8.3 cm AP × 10.7 cm TR × 13.8 cm long). The patient was initially managed conservatively due to stable hemodynamic status and normal hemoglobin levels. However, the patient's clinical status deteriorated and therefore underwent surgical intervention. Exploratory laparotomy confirmed a large intramural hematoma with a ruptured lateral cecal/ascending colonic wall. An open right hemicolectomy with ileocolonic anastomosis was performed. The final pathologic diagnosis was a hemorrhagic infarction of the colon. The patient recovered well and was discharged home 7 days after surgery.
