Venous Thromboembolism in Brain-Dead Organ Donors: A Prospective Study of Prevalence, Management, and Impact on Organ Utilization and Recipient Outcomes.
Observational study in Clinical transplantation, 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
introductionVenous thromboembolism (VTE) is a known complication in critically ill patients, yet its prevalence in deceased organ donors and impact on organ recipients remain poorly characterized. Standardized guidelines for donor VTE assessment and management are lacking.
methodsIn this prospective observational study of brain-dead donors at a regional organ recovery center (October 1, 2021-August 1, 2023), all donors underwent duplex ultrasonography and CT pulmonary angiography to screen for deep vein thrombosis (DVT) and pulmonary embolism (PE). Donors with VTE received prompt therapeutic anticoagulation. Organ recovery data and recipient 1-year survival data were obtained from the Scientific Registry of Transplant Recipients (SRTR). Additionally, we surveyed US organ procurement organizations (OPOs) regarding VTE practices.
resultsAmong 215 donors, 73 (34%) had VTE: 28% with DVT and 14% with PE. All VTE-positive donors received prompt anticoagulation and no bleeding complications were observed. Organ recovery rates and 1-year recipient survival did not differ by donor VTE status. Among 96 survey respondents from 41 of 56 U.S. OPOs, there was substantial variation in VTE practices, only 2% accurately estimated prevalence, and most respondents (83%) supported development of standardized guidelines.
conclusionVTE is common but underrecognized in brain-dead donors. In this observational cohort, prompt diagnosis and short-term management of donor VTE were feasible and were not associated with reduced organ utilization or early recipient outcomes, although the study was not designed to establish treatment efficacy.
