Advancing patient-centered metrics for heart transplantation: The role of days alive and outside the hospital.
Article in The Journal of heart and lung transplantation : the official publication of the International Society for Heart Transplantation, 2025. 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
backgroundHeart transplantation (HT) survival and waitlist times are established outcome metrics. Patient-centered HT outcomes are insufficiently characterized. This study evaluates the role of days alive and outside the hospital (DAOH) as a candidate patient-centered HT performance measure.
methodsThe study cohort included Medicare beneficiaries undergoing HT (July 2008-December 2017). The percent of days outside of hospital (%DOH) 6 months before (%DOH-BF) and percent of days alive outside of hospital 12 months after HT (%DAOH-AF) were evaluated along with adverse events (AEs, early: ≤3 months; late: 4-12 months). Patients were stratified by patient %DAOH-AF terciles. Risk-adjusted %DAOH was evaluated across hospitals.
resultsA total of 5,104 beneficiaries underwent HT across 108 hospitals. Median [interquartile range (IQR)] age was 62 [53-67] years, 23.9% were female, and 21.4% were African-American. The overall median %DOAH-AF was 92.9% [83.8%, 95.9%], varying by tercile: low 71.8% [4.9%, 83.6%], intermediate 92.9% [91%, 94%]; high 96.4% [95.9%, 97.3%]. The lowest (vs highest) tercile %DAOH-AF had a lower median %DOH-BF (88% [73%-97%] vs 92% [81%-98%]) and longer post-HT inpatient stay (54 [36-81] vs 13 [10-15] days). After HT, the lowest versus highest tercile had greater AEs burden in the early (allograft failure [16.1% vs 1.6%], stroke [12.1% vs 2.3%]) and late (stroke [5.1% vs 1.9%], sternal wound infection [5.0% vs 0.8%]) phases post-HT. The mean hospital %DAOH
conclusionsPost-HT %DAOH varies across beneficiaries and hospitals and is associated with AEs. Further research is warranted to assess the role and validity of %DAOH as an HT quality metric.
