Expanding Use of Donation After Circulatory Death Heart Transplantation to Higher Acuity Recipients.
Article in The Annals of thoracic surgery, 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
backgroundDonation after circulatory death (DCD) hearts were initially used more often in medically stable recipients, reflecting both caution for use in higher risk patients and greater availability to lower acuity candidates. We examined temporal trends in DCD recipient characteristics and compared outcomes of DCD with donation after brain death (DBD) transplants, stratified by pretransplant recipient waitlist status.
methodsFrom the United Network for Organ Sharing database (December 1, 2019-December 31, 2023), we identified 12,352 first-time, isolated adult heart transplants (DCD, 1114; DBD, 11,238). Temporal trends in DCD recipient characteristics were analyzed. The primary end point was 1-year posttransplant survival compared between DCD and DBD cohorts after stratifying by pretransplant waitlist status. December 2019 data were combined with 2020.
resultsDCD heart transplantation accounted for 3.6% of all heart transplants in December 2019/2020 and 15.2% in 2023 (P < .001). The proportion of DCD recipients with status 1 and 2 listing increased from 17.6% in December 2019/2020 to 52.6% in 2023, with more frequent use of pretransplant mechanical circulatory support (13.9% to 20.2%; both P < .05). After adjustment, DCD and DBD cohorts had similar 1-year survival irrespective of pretransplant waitlist status (status 1and 2: hazard ratio [HR], 1.12 [95% CI, 0.84-1.51]; status 3: HR, 1.01 [95% CI, 0.63-1.61]; status 4: HR, 0.82 [95% CI, 0.51-1.31]; status 6: HR ,0.88 [95% CI, 0.43-1.80]).
conclusionsThe use of DCD hearts has expanded significantly in higher acuity recipients. One-year survival in these recipients remains equivalent to DBD transplants. With appropriate selection, more aggressive use of DCD donor hearts may be encouraged in higher acuity recipients.
