Transient portal venous gas in upper gastrointestinal bleeding: A case report.
Article in Radiology case reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Portal venous gas (PVG) or hepatic portal venous gas (HPVG) is the accumulation of gas in the portal vein and its branches. HPVG may be considered as a nonspecific sign of a significant abdominal disease, ranging from potentially lethal diseases to benign conditions. Computed tomography (CT) can detect both the presence of gas and the underlying pathology. I report a 60-year-old male who presented to the emergency department with upper gastrointestinal bleeding and a high lactate level in the blood test. Because of the unknown etiology for the elevated lactate, a CT scan of the abdomen was taken, which showed that he developed intra-and extra-hepatic portal venous gas as well as in the portomesentric-portosystemic collaterals without any signs of mesenteric ischemia. The patient was treated conservatively and the HPVG completely resolved after a few days. Overall, physicians must be aware that prognosis is related to the pathology itself and is not influenced by the presence of PVG. HPVG can be caused by several benign conditions that do not necessarily require urgent exploratory laparotomy.
