Barriers and Opportunities to Increase Utilization of Donor Kidneys After Death Determined by Circulatory Criteria Among Children and Adults: A Narrative Review.
Review in Canadian journal of kidney health and disease, 2025. 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
Purpose of Review: Kidney transplantation is associated with survival benefit compared to dialysis. Yet, there is an unmet need for access to kidney transplantation within Canada and globally. Donation after death determined by circulatory criteria (DCC) has expanded access to kidney transplantation among the adult and pediatric population. However, there are concerns inherent to DCC kidneys, including warm ischemia time and ischemia-reperfusion injury (IRI). This narrative review aims to summarize relevant literature in this context, discuss potential opportunities to expand the use of DCC kidneys, and highlight knowledge gaps for further study. Sources of Information: PubMed (Medline), the Canadian Institute for Health Information, and regulatory bodies for organ donation and transplantation. Methods: A focused review and critical appraisal of existing literature on the mechanisms of kidney IRI, consideration of sex in experimental studies relevant to DCC kidney transplantation, ex vivo perfusion strategies, and pediatric kidney transplant considerations. Key Findings: DCC kidneys confer a higher risk of delayed graft function (DGF) due to prolonged warm ischemic time. However, long-term graft survival is generally comparable to that of kidneys from donors with death determined by neurologic criteria (DNC). Key barriers to expansion include the paucity of sex-balanced experimental studies on DCC graft preservation and outcomes and existing protocols for DCC donor selection, including thresholds for warm ischemia time. Ex vivo strategies including non-oxygenated and oxygenated hypothermic machine perfusion and normothermic ex vivo kidney perfusion are promising research areas. Improving DCC protocols to reduce kidney IRI has the potential to further expand access to DCC transplantation, including to the pediatric population. Limitations: This narrative review only included articles written in English. Study quality was not formally assessed. Discussion points were influenced by the author's areas of expertise.
