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

objectivesThe benefit of machine perfusion during storage of liver grafts retrieved after cardiac death should be investigated as applied either at the beginning or near the end of the preservation period.

methodsRat livers were explanted 20 min after cardiac arrest of the donor and cold-stored (CS) for 18 h. Other grafts were additionally subjected to 2 h of normothermic machine perfusion (MP) either 3 h after retrieval (early MP) or 3 h before reperfusion (late MP), thus extending total ischemic time to 20 h. The 3 h period should represent a short transport period between a resident regional pumping center and the explant or implant hospital, respectively. Viability of all livers was assessed thereafter by warm reperfusion in vitro.

resultsIn comparison to the controls, both regimens significantly improved hepatic recovery upon post-preservation reperfusion as evaluated by enzyme release, bile production, and energetic recovery. Molecular upregulation of pro-inflammatory signals was also significantly mitigated. No functional differences between early and late machine perfusion could be disclosed.

conclusionOur data suggest that it might not be necessary to hurry with the attempt to connect the graft to a machine early after retrieval.
