Disparities in Heart Transplantation Allocation and Outcomes by Blood Type in Korea (2010-2022).
Article in Korean circulation journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 AND
objectivesThis study aimed to elucidate the influence of recipient blood type on heart transplant allocation dynamics in Korea, focusing on donor matching, wait times, and post-transplant survival from 2010 to 2022.
methodsIn this retrospective cohort study, we examined 1,745 heart transplant recipients classified by blood types: A (n=631), B (n=488), AB (n=256), and O (n=370). Parameters studied encompassed donor and recipient ages, donor blood type compatibility, organ type, emergency status, waiting periods, and survival rates up to one year post-transplant.
resultsThis investigation revealed significant disparities in the outcomes for heart transplant waitlist patients, differentiated by blood type. O recipients encountered notably extended median wait times of 110 days (an average of 300±514 days), which is substantially longer compared to A (65 days), B (58 days), and AB (29 days). Furthermore, the mortality rate for O recipients while on the waitlist was markedly high at 78.1%, in contrast to 75.2% for A, 72.3% for B, and 48.5% for AB. O recipients who, despite constituting a significant proportion of the donor pool (34.1%), received transplants at disproportionately lower rates.
conclusionsType O heart transplant recipients in Korea face significant challenges, including higher mortality rates during the waiting period and frequent necessity for left ventricular assist device interventions. Urgent policy reforms are needed to address these disparities and improve equitable organ allocation for blood type O patients.
