Waitlist mortality and recovery among pediatric heart transplant candidates in Germany: A nationwide registry analysis.
Article in JHLT open, 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
Background: Clinical outcomes of pediatric heart transplant candidates vary by region due to differences in donor availability and allocation policies. Most registry data originate from North America. We evaluated waitlist mortality, recovery, and associated risk factors among pediatric candidates in Germany. Methods: All candidates < 18 years listed for heart transplantation in the German Transplant Registry (2006-2020) were retrospectively analyzed. Demographic and clinical predictors of mortality and recovery were assessed. Results: Among 780 candidates, 441 (56.5%) underwent transplantation, 140 (17.9 %) died, 12 (1.5%) were withdrawn for deterioration, 61 (7.8 %) recovered, 42 (5.4%) were delisted for undocumented reasons, and 84 (10.8%) remained listed. Mean waiting time was 197 days, longest in children 1-10 years. Candidates that died or were removed were younger (median age 3.1 vs. 6.4 years, p=0.005), smaller, and more likely to have congenital heart disease (CHD, 32.2% vs. 21.3%, p<0.001). Waitlist mortality was higher in children < 2 years (HR 1.496) and in CHD (HR 1.702), while DCM was protective (HR 0.6312). Children < 2 years with diagnoses other than DCM had the highest waitlist mortality (HR 3.3). Recovery occurred in 7.8 %, mainly in infants < 1 year, with younger age and smaller height predicting improvement. ABO-incompatible transplantation was rare (8 cases) despite 278 (38.6 %) being <2 years at listing. Conclusion: Waitlist mortality among pediatric candidates in Germany remains high, particularly in young children with CHD. Broader application of ABO-incompatible transplantation and systematic evaluation for recovery may improve outcomes under persistent donor shortage.
