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

Hepatic encephalopathy (HE) usually occurs in the end stages of cirrhosis. During these stages, portosystemic shunt (PSS) is one cause of severe HE. Previous reports have demonstrated that shunt embolization is effective in cases involving a large PSS. However, embolization is risky in some patients because severe ascites and esophageal varices may result from aggravation of portal hypertension. Herein, we report a case in which intentional flow reduction was repeatedly performed for spleno-renal shunt using 2 flow reduction methods, debranching and the rough coiling technique, for a patient with severe HE for whom embolization of the whole PSS pathway was risky. Complete embolization was finally achieved by repeated flow reduction over 5 sessions. The patient tolerated treatment well with no ascites for 4 years after total embolization. If embolization of the whole PSS puts the patient at risk for refractory HE, repeatable flow reduction might provide a good alternative path to single-step embolization.
