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
BACKGROUNDS/
aimsHemashield vascular grafts has been used for middle hepatic vein (MHV) reconstruction during living donor liver transplantation (LDLT). We occasionally encounter outflow disturbance of MHV conduit at the anastomotic stump of the middle-left hepatic vein (MLHV) trunk. To mitigate the disturbance, we carried out a series of studies regarding hemodynamics-compliant MHV reconstruction.
methodsThis study comprised of three parts: Part 1: Determining the causes of outflow disturbance; Part 2: Computational simulative analysis; and, Part 3: Clinical application of our refined technique. The types of Hemashield conduit-MLHV stump reconstruction were end-to-end anastomosis (type 1), side-to-end anastomosis (type 2), and oblique cutting of the conduit end and patch plasty (type 3).
resultsIn Part 1 study, the reconstruction types were type 1 in 23, type 2 in 25, and type 3 in 2. Significant anastomotic stenosis was identified in 7 (30.4%) in type 1, 6 (24.0%) in type 2, and none (0%) in type 3. The size of MLHV stump was the most important factor for anastomotic stenosis. Through Part 2 study, technical knacks were developed as follows: the conduit end was cut in a dumb-bell shape and a vessel patch attached; and then sutured bidirectionally from the 9 o'clock direction. In Part 3 study, these knacks were applied to 5 patients and none of them experienced noticeable anastomotic stenosis.
conclusionsOur refined technique to perform conduit-MLHV stump anastomosis appears to reduce the risk of anastomotic outflow disturbance for relatively small MLHV stump.
