Why haven't transplant numbers recovered post COVID-19? Evaluating a national cardiothoracic centre.
Article in Irish journal of medical science, 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
backgroundThe COVID-19 pandemic caused significant disruptions to cardiothoracic surgery and transplant services globally, with our initial 2020 study reporting a 50% reduction in activity during March-April 2020. This follow-up assesses persistent impacts and recovery patterns five years post-onset.
methodsA retrospective review of prospectively collected data from a National Cardiothoracic Transplant Unit was conducted for 2019-2025. Annual volumes were compared to 2019 baselines, with subgroup analyses by procedure and acuity.
resultsTotal annual cardiothoracic cases dropped to 49% of 2019 levels in 2021 (251 vs 510) before a gradual recovery: 73% in 2022, 87% in 2023, 91% in 2024, and 96% in 2025. Early pandemic impacts were most pronounced in 2021, with January-April volumes at 27% (40 vs. 149). Procedure-specific trends varied: CABG surgery recovered to 103% by 2024 (319 vs. 309); valve surgery exceeded baseline at 116% by 2025 (116 vs. 100); Aortic surgery reached 78% by 2025. Transplant numbers fell 52% from 2019 to 2020 (52 vs 25) and have failed to increase since, still sitting at half of 2019 volumes. Heart transplants are at 33-67% (5-10 vs 15) and lungs at 35-51% (13-19 vs 37) of pre Covid levels per annum. Acuity remained relatively unchanged during the study period.
conclusionsCardiothoracic surgery volumes largely recovered by 2024, but transplants volume as well as aortic procedures have failed to recover to pre COVID levels. These findings underscore the need for targeted interventions to address backlogs and enhance transplant services in Ireland.
