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
Background: Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by the presence of multiple gas-filled cysts located beneath the intestinal submucosa or plasma membrane. The pathogenesis of PCI remains incompletely understood, and its clinical presentation lacks specificity. Case description: A 69-year-old woman was admitted to the hospital with symptoms of abdominal distension, abdominal pain lasting over 2 weeks, and altered consciousness for 3 days. She had a two-year history of mixed connective tissue disease and was undergoing regular hormone therapy. Upon admission, she demonstrated signs of peritoneal irritation, and computed tomography (CT) revealed the presence of multiple free air pockets within the abdominal cavity, as well as "bead-like" translucent areas within the intestinal wall. An emergency abdominal exploration revealed extensive gas accumulation in the wall of the small intestine and multiple gas bubbles in the mesentery. Subsequently, resection and anastomosis of the affected intestinal section were performed. Postoperative pathology identified multiple non-endothelial cystic cavities within the submucosa and muscularis propria of this segment of the small intestine, with Conclusion: This case report demonstrates the diagnostic difficulties in patients with peritonitis with abdominal free gas in intestinal gas cysts, reveals the potential role of abnormal intestinal flora, especially the never reported colonization by Phocaeicola vulgatus, in the development of PCI combined with abdominal free gas.
