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

Congenital extrahepatic portosystemic shunts are a rare cause of lower gastrointestinal bleeding in children. They result from the connection of a systemic vessel with the portomesenteric vasculature before the division of the main portal vein. Herein, we report a case of a congenital extrahepatic portosystemic shunts type II in a 4-year-old male diagnosed by Doppler ultrasonography during the investigation of abdominal pain and recurrent hematochezia, later confirmed by computed tomography. Conventional angiography with a balloon occlusion test revealed patent intrahepatic portal branches not depicted by previous imaging techniques. Successful shunt closure was achieved by endovascular approach with an Amplatzer Septal Occluder without complications.
