Variations of the right branch of hepatic portal vein in children based on three-dimensional simulation technology.
Article in Surgical and radiologic anatomy : SRA, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
purposeTo study the variations of the right branch of the hepatic portal vein in children.
methodsA total of 810 children's abdominal CT images were reconstructed with three-dimensional (3D) simulation software, Variations of the right branch of the hepatic portal vein were analyzed and classified.
resultsThe most common anatomy (type A) was seen in 355 patients (43.83%). Trifurcation in the right anterior portal vein (type B) variation was seen in 250 cases (30.86%). The right posterior portal vein arched without obvious branching (type C) was seen in 71 cases (8.77%). There were 134 special variants (16.54%) named type D, including 14 cases (1.73%) with the right anterior branch in four sub-branches, 13 cases (1.60%) in one trunk and multiple sub-branches, 92 cases (11.36%) originating from the left trunk of the portal vein, and 15 cases (1.85%) with the VI segment of the portal vein originating from the right anterior branch of the portal vein.
conclusionVariations in the right branch of the hepatic portal vein seems to be very frequent. Recognition of such variations is important in the preoperative evaluation of children with surgery planned, because these variations may have implications for anatomy-guided liver resection and for planning the operative approach.
