High Rate of Transplantation Before Review of Status Exception Requests Among Adult Heart Transplant Candidates.
Article in Circulation. Heart failure, 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
backgroundIn the US heart allocation system, when transplant centers submit applications for status exceptions to increase waitlist priority, patients obtain the requested status upgrades immediately while their applications are sent to the regional review boards (RRBs) and reviewed retrospectively. How often transplants occur during this period is unknown.
methodsUsing the Scientific Registry of Transplant Recipients, we identified all adult heart transplant candidates listed between October 18, 2018, and May 31, 2025, with submitted applications for status exceptions. We assessed (1) the time elapsed between submission of exception applications and their receipt by the RRBs and (2) the rate of heart transplantation during this travel time, stratified by whether the applications were eventually approved or denied. Additionally, we estimated how many listed patients were skipped by candidates who received transplants with exceptions that were ultimately denied.
results138 transplant centers submitted status exception requests on behalf of 11 508 adult candidates during the study period, of whom 913 (7.9%) received a denial at least once. The median time from obtaining status upgrades to application receipt by the RRBs was 3 days. Three thousand seven out of 11 508 (26.1%) patients received transplants before the RRBs even received their applications, with 174 (19.1%) among 913 with eventual denials and 2833 (26.7%) among 10 595 with approvals. The cumulative incidence of heart transplantation before application receipt for eventual denials was 19.1% (95% CI, 16.6%-21.7%), and that for approvals was 27.2% (95% CI, 26.4%-28.0%;
conclusionsMore than 25% of patients with status exception requests receive heart transplants before their applications are even received by their RRBs, raising significant concerns about the fairness of retrospective review of exception requests for the allocation of donor hearts.
