Baseline Portal Vein Thrombosis does not Worsen Long-Term Outcomes After Technically Successful TIPS in Cirrhotic Variceal Bleeding: A Single-Center Retrospective Cohort Study.

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
purposeTo investigate whether the presence of baseline portal vein thrombosis (PVT) and its anatomical subtypes influence long-term outcomes in cirrhotic patients with esophagogastric variceal bleeding (EGVB) undergoing technically successful transjugular intrahepatic portosystemic shunt (TIPS). MATERIALS AND
methodsThis retrospective cohort study included 140 cirrhotic EGVB patients who underwent successful TIPS between 2017 and 2024. Patients were stratified into groups with (n = 52) and without baseline PVT (n = 88) based on cross-sectional imaging. PVT was subclassified into simple (main trunk only) and mixed (extending to branches/mesenteric veins) types. The primary composite endpoint included all-cause mortality, variceal rebleeding, or shunt dysfunction. Kaplan-Meier analysis and multivariable Cox regression were performed.
resultsMedian follow-up was 1286 days. Composite endpoint events occurred in 59 patients (42.1%), with no significant difference between patients with and without PVT (40.4% vs. 43.2%, P = 0.742). Cumulative event-free survival was comparable (log-rank P = 0.650). Within the PVT cohort, no difference was observed between simple and mixed subtypes (HR = 0.80, P = 0.736). Multivariable analysis confirmed that baseline PVT was not an independent predictor of adverse outcomes (HR = 0.92, P = 0.799). However, higher baseline portal pressure gradient (PPG) (HR = 1.09 per mmHg, P = 0.002) and prior history of overt hepatic encephalopathy (OHE) (HR = 3.33, P = 0.040) were identified as independent predictors.
conclusionsBaseline PVT, regardless of morphological subtype, does not appear to adversely affect long-term outcomes in the specific cohort of patients in whom TIPS is technically feasible and successful. Higher baseline PPG and history of OHE are primary determinants of long-term prognosis.
