Novel Approach via the Round Ligament in Portal Vein Embolization.
Article in World journal of surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundThe objective of this study was to describe the detailed technique and clinical outcomes of portal vein embolization via the round ligament (RL-PVE) prior to major hepatectomy.
methodsBetween January 2010 and March 2020, a total of 50 portal vein embolization (PVE) procedures were performed in 50 patients. Of them, seven patients who underwent RL-PVE were enrolled in this study. Percutaneous transhepatic portal vein embolization (PTPE) was not indicated due to the following reasons: bile duct dilation (n = 4), difficulty in visualizing the portal vein on ultrasonography because of severe fatty liver (n = 1), large tumor size (n = 1), and combined surgery with staging laparoscopy (n = 1). The following were reasons for avoiding trans-ileocecal PVE: past laparotomy (n = 5), difficulty in accessing the portal vein due to a large tumor (n = 1), and purpose of preventing small intestinal adhesions before hepatopancreatoduodenectomy (n = 1). The percentage of functional hepatic remnant rates was calculated before and after RL-PVE.
resultsTechnical success was achieved in all cases. Five patients underwent embolization of the right portal vein, while two underwent embolization of the left portal vein. The median operative time and blood loss during RL-PVE were 181 min and 33 g, respectively. Morbidity and mortality related to RL-PVE were not observed. The median functional hepatic remnant rate before and after PVE was 55.6% and 63.2%, respectively. Liver functions including Child-Pugh classification were equivalent before and after RL-PVE.
conclusionsThe RL-PVE technique may be useful in elective cases for which it is difficult to safely perform PTPE or trans-ileocecal approaches.
