Balloon-occluded Retrograde Transvenous Obliteration for Gastric Varices Draining into the Gastrocaval Shunt.
Article in Interventional radiology (Higashimatsuyama-shi (Japan), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The left inferior phrenic vein has two orifices and consists of transverse and vertical parts. A total of 10%-15% of fundal gastric varices drain into the gastrocaval shunt, a hypertrophied transverse part of the left inferior phrenic vein. The outlet of the gastrocaval shunt is occasionally kinked and stenotic, and the transverse part of the left inferior phrenic vein is usually connected to several vessels. Additionally, portopulmonary venous anastomosis is occasionally accompanied by gastric varices draining into the gastrocaval shunt without developing a gastrorenal shunt. These anatomical characteristics make it difficult to embolize gastric varices draining into the gastrocaval shunt with balloon-occluded retrograde transvenous obliteration. We describe fundamental techniques for catheterizing and obliterating gastric varices draining into the gastrocaval shunt using 5% ethanolamine oleate.
