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
Congenital intrahepatic portosystemic shunts are uncommon vascular anomalies that can lead to hyperammonemia and liver dysfunction. We report a 48-year-old woman with a large intrahepatic shunt presenting with elevated blood ammonia and progressive hepatic atrophy. She underwent percutaneous coil-in-plug embolization using an Amplatzer Vascular Plug II filled with coils. Four-dimensional Flow MRI performed before the procedure and at 2 days and 6 months afterward demonstrated complete shunt occlusion, restoration of normal portal flow, and increased liver volume. Her ammonia level normalized within 1 day, and the patient remained asymptomatic. This case highlights the safety and efficacy of the coil-in-plug technique for large intrahepatic shunts and underscores the utility of four-dimensional Flow MRI for treatment planning and follow-up.
