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
We reported a case of portal vein pneumatosis caused by a nasojejunal nutrition tube that was successfully treated conservatively. This patient was discharged after 1 week of treatment with imipenem/cilastatin sodium for anti-infection, gastrointestinal decompression, fluid replacement, and pain relief, and the patient's abdominal pain was significantly relieved. The main pathogenesis of hepatic portal venous gas is as follows: (a) increased pressure in the digestive tract leading to gas entering the portal vein circulation through the intestinal wall and finally into the liver; (b) destruction of the intestinal mucosa causing the gas formed by intestinal bacteria to enter the portal vein system; and (c) diffusion of gas produced by bacteria in intraperitoneal abscesses or portal vein and mesentery, causing pyelitis. The successful treatment of this patient highlights that addressing physical factors, providing gastrointestinal decompression, and administering anti-infection therapy can aid in the management of such cases. Bacterial culture of gastric juice and drug sensitivity testing can guide effective anti-infection treatment.
