Current status and geographic inequities in solid organ and corneal transplantation in Ecuador (2010-2022).
Article in PeerJ, 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
Background: Organ and tissue transplantation is an essential therapy for end-stage disease. However, in Ecuador, systematic evidence on waiting list dynamics, demographic and clinical patterns, and equity in access remains scarce. The absence of comprehensive analyses has limited the capacity to identify disparities and to inform evidence-based allocation policies. Objective: This study aimed to characterize the national transplant waiting list in Ecuador from 2010 to 2022, to assess demographic, clinical, and geographic disparities to provide insights into donor-recipient compatibility and equity in allocation. Study Design: We conducted a retrospective cohort study using data from the Ecuadorian National Institute for Organ and Tissue Donation and Transplantation (INDOT). The dataset included all patients listed for kidney, liver, heart, lung, and corneal transplants between 2010 and 2022. Variables analyzed included age, sex, comorbidities, geographic origin, and mortality while on the waiting list. Descriptive statistics were used to characterize the population and compare trends across organ types. Results: A total of 6,523 individuals were listed during the study period: 59% for corneal, 35.7% for kidney, 4.9% for liver, 0.3% for heart, and 0.06% for lung transplantation. Men predominated in corneal (72.3%) and heart (72.7%) lists, whereas women predominated in kidney (61%) and liver (57%) lists. Overall mortality while on the waiting list reached 21.3%. Geographic disparities were evident, with most transplant programs concentrated in Quito, Guayaquil, and Cuenca. Conclusions: This nationwide study demonstrates persistent inequities in Ecuador's transplant system reflected in geographic concentration, sex-specific trends, and mortality among kidney and liver candidates. Findings highlight the need to expand programs beyond major cities, strengthen donor identification strategies, and integrate clinical, socioeconomic, and genetic factors into allocation policies.
