1 · What the graph read from it

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.

2 · The registry

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

Non-tumoral portal vein thrombosis (PVT) is a frequent and challenging complication in liver transplant candidates. The prevalence reaches up to 26% in patients with cirrhosis on a transplant waiting list. Its severity increases with liver disease progression and significantly impacts post-transplant outcomes. Advanced PVT increases postoperative mortality to 30%. Effective management requires a multidisciplinary approach, especially in advanced cases. Preoperative strategies emphasize anticoagulation with low molecular weight heparin, while interventional radiology, including transjugular intrahepatic portosystemic shunts, offers alternatives in some cases. Intraoperatively, management is guided by PVT classification systems, ranging from thrombectomy and portal vein reconstruction to non-physiological reconstructions in complex cases. This manuscript explores the management of PVT in liver transplantation candidates, discusses strategies to optimize outcomes, and presents our institutional protocol for addressing this high-risk condition.
