Early outcome of machine perfusion vs static cold storage of liver graft: A systemic review and meta-analysis of randomized controlled trials.
Review in Hepatology forum, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The use of marginal grafts is very challenging and is associated with post-reperfusion syndrome and early allograft dysfunction. The outcomes of machine perfusion for the preservation of marginal grafts have been compared with that of static cold storage, with studies reporting a reduced risk of ischemic cholangiopathy and graft loss. We performed this systematic review and meta-analysis of randomized controlled trials (RCTs) comparing outcomes of machine perfusion of liver grafts to static cold storage (SCS) of liver grafts during liver transplantation. Two independent researchers thoroughly searched for literature in the following databases: PubMed (Medline), Cochrane Central Register of Controlled Studies (CENTRAL), clinical trial registry, ResearchGate, Google Scholar, and Scopus (ELSEVIER) databases (last search: November 2023). The search terms used were: "dynamic perfusion," "normothermic perfusion," "hypothermic perfusion," "liver transplantation," "static cold storage," "NMP," "HOPE," "extended criteria grafts," "marginal grafts," "RCTs," "randomized controlled trials," "warm ischemia," and "cold ischemia." Eight RCTs published between 2019 and 2023 were included in the data synthesis and meta-analysis. The primary outcome considered was the overall incidence of early allograft dysfunction (EAD) between the two methods of graft perfusion after liver transplantation. The secondary outcome considered was the rate of retransplantation. Our meta-analysis revealed that SCS is associated with more EAD when compared with machine perfusion, with a p-value of <0.00001. We also found that the rate of retransplantation is higher among patients who received a liver preserved by SCS, with a p-value of 0.02. The use of machine perfusion in the preservation of liver grafts showed a significant reduction in early allograft dysfunction and retransplantation.
