Right portal branch to ovarian vein anastomosis: An unusual portosystemic shunt secondary to pelvic venous congestion.
Article in Radiology case reports, 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
Spontaneous portosystemic shunts in noncirrhotic patients are rare vascular anomalies and may present a diagnostic challenge. We report a rare right-sided spontaneous porto-ovarian venous communication in a 35-year-old woman presenting with symptoms of pelvic venous congestion. Contrast-enhanced CT performed during the portal venous phase demonstrated a segmental branch of the right portal vein anastomosing with a markedly dilated and tortuous right ovarian vein, associated with parametrial and pelvic varices. The right ovarian vein was traced inferiorly and confirmed to drain into the inferior vena cava. The main portal vein and intrahepatic branches were patent, with normal hepatic enhancement and no imaging evidence of cirrhosis, portal thrombosis, or portal hypertension. To our knowledge, only 1 similar case involving the left ovarian vein has been reported in indexed literature. Recognition of this rare porto-ovarian communication is essential to avoid diagnostic pitfalls and to guide appropriate management strategies in patients presenting with pelvic venous congestion.
