1 · What the graph read from 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.

2 · The registry

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

purposeThe incidence of post-transplant poral vein stenosis (PVS) is higher in pediatric liver transplantation, probably resulting from various portal vein (PV) reconstruction methods or other factors.

methods332 patients less than 12 years old when receiving liver transplantation (LT) were enrolled in this research. Portal vein reconstruction methods include anastomosis to the left side of the recipient PV trunk (type 1, n = 170), to the recipient left and right PV branch patch (type 2, n = 79), using vein graft interposition (type 3, n = 32), or end-to-end PV anastomosis (type 4, n = 50). The incidence of PVS was analyzed in terms to different PV reconstruction methods and other possible risk factors.

resultsPVS occurred in 35 (10.5%) patients. Of the 32 patients using vein graft, 20 patients received a cryopreserved vein graft, 11 (55%) developed PVS, while the remaining 12 patients received a fresh iliac vein for PV interposition and none of them developed PVS. 9 patients whose liver donor was under 12 years old developed PVS, with an incidence of 18.8%.

conclusionCryopreserved vein graft interposition and a liver donor under 12 are independent risk factors for PVS in pediatric LT.
