Preduodenal portal vein: two distinct case reports with unique presentations and tailored surgical management strategies.
Article in Journal of surgical case reports, 2025. 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
Preduodenal portal vein (PDPV) is a rare congenital vascular malformation, which was first described by Knight in 1921 as an anomalous vein that lies in front of the duodenum, common bile duct, and hepatic artery instead of beneath them. This abnormal position may result in congenital duodenal obstruction and puts it in danger during operations around this region. PDPV is typically associated with other congenital anomalies, mainly intraabdominal and cardiac ones. The surgical management is usually determined intraoperatively based on evidence that the PDPV is the real cause of obstruction. We report two cases of PDPV each with a different presentation and management approach.
