Patient with Acute-On-Chronic Cholecystitis Complicated by Portal Vein Thrombosis Following "Long COVID-19": A Case Report.

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
Portal vein thrombosis (PVT) is a rare but serious complication of hypercoagulable states or conditions that increase portal pressure, such as liver cirrhosis, inherited or acquired coagulation cascade abnormalities, myeloproliferative disorders, malignancy, inflammation, or infection. COVID-19 has been associated with a prothrombotic state, leading to both arterial and venous thromboses. Here, we present a patient with minimal hypercoagulable risk factors who presented with PVT and acute-on-chronic cholecystitis with bacteremia, likely provoked by residual hypercoagulability from a "long COVID-19" syndrome. An 81-year-old male developed PVT as a complication of acute-on-chronic cholecystitis, with contributing factors potentially including hypercoagulability related to prior COVID-19 infection more than 4 months prior. PVT should remain a diagnostic consideration in patients with various hypercoagulable risk factors, including long COVID-19, who present with relevant clinical findings. There should be a low threshold for the pursuit of further diagnostic imaging, given the serious consequences of delayed diagnosis.
