Effect of multi-artery renal grafts on patient outcomes in living donor kidney transplantation.
Article in Langenbeck's archives of surgery, 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
backgroundMultiple renal arteries (MRA) in a donor kidney can increase surgical complexity in living donor kidney transplantation. However, the impact of MRA on early transplant outcomes, including delayed graft function (DGF) and early graft failure, remains unclear.
methodsWe performed a single-center retrospective cohort study of 1,200 living donor kidney transplants conducted between 2019 and 2024. Donor kidneys were classified as having a single renal artery or multiple renal arteries (two or more). Recipient and donor characteristics, intraoperative details (ischemia times, vascular anastomosis technique), and postoperative outcomes (delayed graft function [DGF], primary nonfunction, and graft survival) were compared between the two groups. Logistic regression analyses were used to examine associations between MRA and the risk of DGF or graft failure within the first 90 days, both before and after adjusting for prespecified covariates.
resultsOf the 1,200 transplanted kidneys, 882 (73.5%) had a single artery and 318 (26.5%) had multiple arteries. Although the median cold-ischemia time was longer for multi-artery grafts (35.2 min vs. 29.4 min, p = 0.004), there were no significant differences in donor or recipient baseline characteristics. Multivariable logistic regression revealed no significant association between MRA and either DGF or early graft loss. Kaplan-Meier curves, censored for death, demonstrated similar graft survival in both groups (log-rank p = 0.25).
conclusionsIn this single-center cohort of living donor kidney transplants, grafts with multiple renal arteries did not exhibit an elevated risk of DGF or early graft loss. While additional surgical complexity is often required for MRA grafts, our findings suggest that these kidneys remain a safe and effective option for transplantation, supporting their broader use to expand the donor pool.
