Exercise capacity after mechanical circulatory support compared to heart transplant in advanced heart failure.
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: In patients with advanced heart failure, it is assumed that orthotopic heart transplant (OHTx) results in greater exercise capacity compared to ventricular assist device (VAD), however this has not been formally examined. In this study, we evaluated the exercise capacity of patients following VAD and OHTx after a structured outpatient rehabilitation program. Methods: We performed a retrospective single-center cohort study of patients undergoing OHTx or VAD at a tertiary centre from January 2022 to January 2024. Comorbidities and the option of either intervention was used as inputs in a multivariate linear regression model for prediction of 3-month 6-minute walk test (6MWT). Major factors identified were added as covariates in the combined cohort to determine predictors of 6MWT. Results: A total of 78 patients were included. The maximal recorded 6MWT was similar between both cohorts (median 6MWT OHTx: 534.0 (478.8-600.3)m; VAD: 608.5 (487.0-643.5)m, Conclusions: In patients with advanced heart failure, VAD and OHTx are associated with a similar level of exercise capacity and does not impact exercise capacity in patients undergoing OHTx who are bridged with a VAD. In patients with OHTx, gender was the strongest predictor of exercise capacity.
