Geospatial Insights into Access to Kidney Transplantation in Underserved Hispanic Communities.
Article in Journal of racial and ethnic health disparities, 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
introductionThe rising Hispanic population in the U.S. is at significant end-stage kidney disease (ESKD) risk. However, Hispanic communities face notable challenges in kidney transplantation access. We aimed to identify U.S. regions that might lack kidney transplant centers (KTCs) actively engaging Hispanic individuals living with ESKD.
methodsWe identified location of U.S. KTCs using the UNOS database from 2018 to 2022. We examined county-level prevalence and mortality of adult Hispanic individuals living with ESKD from the 2021 public USRDS dataset. We performed geospatial analysis to characterize the Hispanic population within a two-hour drive from each KTC, and identified statistically significant spatial hot and cold spot clustering for our variables of interest. Additionally, we identified KTCs with dedicated Hispanic kidney clinics (H-KTC) and analyzed pre- and post-implementation transplantation rates.
resultsWe included 196 KTCs and 11 H-KTCs. Geospatial analysis showed that there was a higher proportion of Hispanic individuals living with ESKD outside the two-hour driving zone than within the two-hour driving zone (0.23% vs. 0.21. Death count among Hispanic individuals living with ESKD was 11.4% outside vs. 10.2% within 2-h driving zone, with mortality rate > 10Std-Dev in some south-west regions of US out of the 2 h-driving zones. After H-KTC implementation, the median transplants per center among Hispanic recipients increased from 81 [IQR 58-146.5] to 109 [IQR 66-178.5] (p = 0.006).
conclusionAlthough the existing KTCs serving Hispanic populations are located within strategic geographic locations, there are still areas with a high prevalence of Hispanic individuals living with ESKD with limited access to KTCs. These populations might benefit from extensive outreach from new or existing KTCs.
