Platelet aggregation as a thrombotic marker in cirrhotic patients with portal vein thrombosis.

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
Aim of the study: Portal vein thrombosis (PVT) is frequently observed in liver cirrhosis patients and correlates with the severity of the underlying liver disease. Thrombocytopenia and thrombocytopathy are signs of liver cirrhosis. A disruption in platelet function may have an impact on the development of thrombosis, considering that platelets are essential in the formation of thrombosis. Previous studies on platelet function in liver disease have not been conclusive; therefore, this study aimed to evaluate Material and methods: The study included 100 subjects (30 cirrhotic patients with PVT, 40 cirrhotic without PVT, and 30 healthy individuals as a control group). Platelet function was evaluated using light transmission aggregometry (LTA) in addition to serum von Willebrand factor antigen (vWF-Ag) to assess the platelet activation and adhesion function. Results: Platelet aggregation was decreased in response to aggregating agonists (ADP and ristocetin) in cirrhotic patients with and without PVT compared to healthy controls. Notably, among cirrhotic patients, platelet aggregation was higher in those with PVT compared to those without. Univariate analysis identified six PVT-associated factors: Child-Pugh classification ( Conclusions: Platelet aggregation is significantly higher in cirrhotic PVT patients compared to non-PVT patients. Additionally, elevated vWF-Ag level is an independent risk factor for PVT development in cirrhotic patients. These findings suggest the role of platelet activation in the pathogenesis of PVT and could enhance critical care strategies in patient management and prevention of PVT.
