Pushing the Limit for Marginal Grafts in the Era of Machine Perfusion: A Tale of HOPE From a Leading Italian Institution.
Article in Artificial organs, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 advent of machine perfusion (MP) has significantly improved post-liver transplantation (post-LT) outcomes, potentially enabling the use of increasingly marginal grafts and expanding the organ donor pool.
methodsWe present a retrospective cohort study of consecutive adult patients who underwent LT between 2018 and 2023 at a leading Italian institution. The objective was to evaluate outcomes following the use of hypothermic oxygenated perfusion (HOPE) in high-risk grafts.
resultsA total of 507 patients were included in the final analysis, of whom 420 (83%) received extended criteria donor (ECD) grafts. Among ECD grafts, 62 (15%) were from donation after circulatory death (DCD) donors, and 64 (15%) were previously discarded by other centers. HOPE was applied in 248 (49%) cases. Recipients in the HOPE group experienced significantly lower rates of early allograft dysfunction (EAD) (20% vs. 32%, p = 0.007), primary nonfunction (2% vs. 7%, p = 0.017), and severe postoperative complications (Clavien-Dindo grade ≥ 3b) (19% vs. 28%, p = 0.026). Notably, marginal grafts treated with HOPE achieved survival outcomes comparable to those of standard risk.
conclusionsHOPE is associated with improved outcomes in LT using ECD grafts and can enable the safe use of higher-risk organs with acceptable results when performed in experienced centers.
