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
Objective: To analyze the clinical characteristics, etiological distribution, and treatment outcomes of Hepatic Portal Venous Gas (HPVG) in a cohort of elderly patients with multiple comorbidities, and to evaluate the impact of early surgical intervention on survival rates. Methods: A retrospective study was conducted on 25 patients with HPVG admitted to Taixing People's Hospital of Yangzhou University from January 2010 to June 2024. The study included demographic characteristics, symptoms, comorbidities, etiology, laboratory and abdominal CT results, treatment, and outcomes. Results: The male-to-female ratio was 2.6:1, with a median age of 62 years. Common symptoms included abdominal pain (88%), vomiting (44%), and septic shock (36%). Comorbidities included coronary heart disease (52%), type 2 diabetes (64%), and hypertension (76%). Leukocytosis was observed in 84% of patients. Abdominal CT scans revealed HPVG in all patients. Etiologies included intestinal ischemia/necrosis (56%), intestinal obstruction (24%), suspected intestinal perforation (12%), and intestinal inflammation (8%). Treatment involved emergency surgery combined with antibiotic therapy in 72% of patients and conservative management in 28%. Outcomes showed 60% effectiveness and 40% mortality. Among the surgical group, 12 patients recovered and 6 died; among the conservative group, 3 recovered and 4 died. Conclusion: HPVG has complex etiologies, and abdominal CT is the recommended diagnostic method. Patients with acute abdomen should undergo surgery as soon as possible to improve prognosis, although some cases have poor prognosis.
