Pneumatosis cystoides intestinalis misdiagnosed as pneumoperitoneum due to colon perforation in a patient with blunt trauma injuries: a case report.
Article in Journal of trauma and injury, 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
A laparotomy is usually performed when pneumoperitoneum is identified on abdominal computed tomography (CT) in patients with trauma-related injuries. However, in rare cases, pneumatosis cystoides intestinalis (PCI) may be misinterpreted as free air due to bowel perforation. PCI typically follows a benign course and can be managed with physical examinations and imaging studies. In this case, however, the patient was comatose from a severe traumatic brain injury, rendering the physical examination unreliable. Abdominal CT revealed multiple extraluminal air foci in the retroperitoneal space surrounding the ascending colon, consistent with pneumoperitoneum. No evidence of intraoperative peritonitis was found. Nevertheless, because bowel perforation could not be definitively excluded, a right hemicolectomy was performed, and histopathological examination confirmed PCI.
