Nomogram model for identifying portal vein thrombosis in patients with decompensated cirrhosis.
Article in European journal of gastroenterology & hepatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
aimsVon Willebrand factor (vWF) plays a key role in hemostasis and is reported to be related to the outcome of advanced chronic liver disease. The present study aimed to investigate the relationship between vWF and other potential variables and portal vein thrombosis (PVT) in patients with decompensated cirrhosis.
methodsConsecutive cirrhotic patients with gastroesophageal varices were admitted to our hospital between January 2020 and September 2022. Patients were prospectively recruited and divided into PVT and non-PVT groups. We collected clinical tests, biochemical tests, coagulation tests, and hemostatic protein profile data to explore the associated factors of PVT.
resultsA total of 128 patients were enrolled including 60 patients with PVT and 68 patients without PVT. Plasma levels of vWF [odds ratio (OR) = 1.015, 95% confidence interval (CI): 1.005-1.025, P = 0.005], D-dimer (OR = 1.967, 95% CI: 1.141-3.389, P = 0.015), and decreased portal vein velocity (PVV) (OR = 0.852, 95% CI: 0.769-0.944, P = 0.002) were the variables independently associated with the existence of PVT. Area under the curve (AUC) analyses for vWF, D-dimer, and PVV were 0.779, 0.848, and 0.832, respectively. A nomogram model was established involving the three parameters, and the AUC was 0.919 (95% CI: 0.869-0.969). In the internal validation using bootstrap, the AUC was 0.919 (95% CI: 0.868-0.970).
conclusionHigher vWF levels were related to PVT in patients with decompensated cirrhosis, indicating that vWF might serve as a relevant factor for PVT, and a nomogram containing vWF, D-dimer, and PVV could be an important tool for PVT identification in cirrhotic patients.
