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
objectivesThe transjugular intrahepatic portosystemic shunt procedure remains technically challenging in cases involving occlusion of the portal trunk. This study aimed to evaluate the feasibility, efficacy, and safety of utilizing the inferior vena cava-splenic vein shunt (IVCSS) as a new treatment option in cirrhotic patients with complete portal trunk occlusion and portal cavernoma.
methodsThe IVCSS procedure was performed on twelve patients, involving the creation of a shunt using a covered stent between the inferior vena cava and the proximal end of the splenic vein to reduce distal portal pressure.
resultsTechnical success was achieved in all patients, with a mean procedure duration of 71.7 ± 44.2 min. The portosystemic gradient was reduced by a mean of 11.0 ± 5.6 mmHg after the procedure. After a median follow-up of 6.7 [2.8-11.4] months, clinical symptoms improved in all patients. Stent dysfunction occurred in 1 patient, the recurrence rates for variceal bleeding and ascites were 8.3% and 16.7%, respectively. One patient (8.3%) experienced a procedure-related complication of retroperitoneal hemorrhage. Three patients (25%) had an episode of hepatic encephalopathy, which improved after conservative treatment.
conclusionIVCSS effectively reduced distal portal pressure, which contributed to an improvement of the patients' clinical symptoms with an acceptable procedure-related complication rate. IVCSS may serve as an alternative strategy to manage symptomatic portal hypertension for patients with complete portal trunk occlusion and portal cavernoma. KEY POINTS: Question What is an alternative treatment for cirrhotic patients with symptomatic portal hypertension caused by chronic portal vein occlusion other than TIPS? Findings Inferior vena cava-splenic vein shunt (IVCSS) is feasible for reducing distal portal pressure and effectively improving clinical symptoms. Clinical relevance For cirrhotic patients with complete portal trunk occlusion and portal cavernoma, the IVCSS approach seemed to be a promising alternative treatment for symptomatic portal hypertension.
