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

Abernethy malformation is a rare congenital extrahepatic portosystemic shunt resulting from the persistence of embryonic vessels in the splanchnic venous system. There are 2 known types of Abernethy malformations: type I and II; both of which involve aberrant drainage of the portal venous blood into the inferior vena cava. Here, we detail the anatomy as well as clinical, surgical, and interventional management of 4 patients with Abernethy malformations. In addition, we detail a patient with a previously undescribed anatomic variant of the Abernethy type II malformation: a portosystemic shunt into an interrupted inferior vena cava in which central venous return was provided through the azygous/hemiazygos system.
