Effect of portal pressure gradient reduction on outcomes after transjugular intrahepatic portosystemic shunt in portal hypertension patients.

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
backgroundPortal hypertension (PHT), a complication of liver cirrhosis, is sometimes managed with transjugular intrahepatic portosystemic shunt (TIPS) to reduce portal pressure. Although effective, TIPS poses risks, including hepatic encephalopathy (HE). This study investigates whether a significant reduction in the portal pressure gradient (PPG) after TIPS improves outcomes in PHT patients.
aimTo evaluate the impact of post-TIPS PPG reduction on clinical outcomes and explore the relationship between PPG reduction and portal vein diameter.
methodsThis retrospective cohort study included 815 patients with PHT who underwent TIPS at two tertiary hospitals between 2014 and 2022. Patients were categorized based on whether they achieved a 50% reduction in PPG. Propensity score matching was applied to balance baseline characteristics. Kaplan-Meier analysis assessed clinical outcomes, including rebleeding, HE, liver failure, and hepatocellular carcinoma. Cox regression identified risk factors, and Spearman correlation analyzed the relationship between PPG reduction and portal vein diameter.
resultsPatients with a PPG reduction > 50% had significantly lower risks of rebleeding (
conclusionA significant PPG reduction following TIPS is associated with improved clinical outcomes, including reduced risks of rebleeding, shunt dysfunction, hepatocellular carcinoma, and mortality, though it increases HE and liver failure risks. The observed correlation between portal vein diameter and PPG reduction highlights the potential role of portal vein anatomy in predicting TIPS efficacy, warranting further investigation.
