Evaluating outcomes of preemptive kidney transplant in patients over 65 using high-KDPI kidneys compared to non-preemptive recipients.
Article in International urology and nephrology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundUtilizing kidneys with a Kidney Donor Profile Index (KDPI) score above 85 could be beneficial, especially in End-Stage Kidney Disease (ESKD) patients older than 65. Our study aimed to assess the outcomes of preemptive kidney transplants (KT) in these patients over 65 receiving high KDPI kidneys (≥ 85) and compare the outcomes to the non-preemptive kidney recipients. METHODS AND MATERIALS: This retrospective cohort analyzed the SRTR database for KTs that were performed in the United States from January 2000 to May 2023. This study includes patients older than 65 years old who received only deceased donor KTs, excluding those waitlisted or with prior organ transplants and missing in KDPI scoring. Participants were categorized into four groups: high KDPI preemptive, low KDPI preemptive, high KDPI non-preemptive, and low KDPI non-preemptive. Time-to-event models were used to assess death censored graft loss, and death, adjusting for recipients and donors variables.
resultsA total of 47,077 patients aged 65 years and older were included. The median age of the study population was 69 (interquartile rang: 66 - 72) years old and the median follow-up time was 3.1 years. In multivariable Cox regression model, high KDPI non-preemptive transplantation was associated with the worst survival for death censored allograft failure compared to the low KDPI preemptive group, in the presence of confounding variables (HR: 2.89 95% CI: 2.58-3.24). This was followed by the high KDPI preemptive group (HR: 1.88, 95% CI: 1.54-2.30) and low KDPI non-preemptive group (HR: 1.52, 95% CI: 1.37-1.68). Similarly, the high KDPI non-preemptive group had the worst patients' survival outcomes (HR: 1.80, 95% CI: 1.61-2.02), followed by the low KDPI non-preemptive (HR: 1.47, 95% CI: 1.33-1.63), and the high KDPI preemptive group (HR: 1.28, 95% CI: 1.05-1.57).
conclusionOlder patients can benefit from KT, even when receiving a high-KDPI kidney. Long-term patient survival in older individuals who received high-KDPI kidneys is comparable to low-KDPI recipients. Additionally, preemptive KT led to better outcomes, even in high KDPI cases, underscoring the importance of transplant timing.
