Frailty is associated with poorer health-related quality of life among adult heart transplant recipients: a cross-sectional study.
Article in BMC cardiovascular disorders, 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
backgroundFrailty has recognized prognostic value in cardiovascular disease, but its relationship with health-related quality of life (HRQoL) after heart transplantation remains poorly characterized in middle-income settings. This study evaluated frailty and HRQoL among adult heart transplant survivors.
methodsWe conducted a cross-sectional analysis of adult heart transplant recipients at a national referral center in Colombia. HRQoL was assessed using the EuroQol 5-Dimension 3-Level instrument, and frailty was evaluated using a self-reported FRAIL scale administered by telephone. Participants were classified as non-frail, prefrail, or frail. EQ-5D index scores were compared using Bonferroni-corrected pairwise tests. Multivariable linear regression with robust standard errors was used as an exploratory analysis.
resultsSeventy-three recipients were included: 39 non-frail, 29 prefrail, and 5 frail. EQ-5D index scores decreased across frailty categories. Non-frail participants had higher scores than prefrail and frail participants, and prefrail participants had higher scores than frail participants. In exploratory multivariable analysis, frail participants showed lower HRQoL scores than non-frail participants (β = -0.19; 95% CI, - 0.32 to - 0.06; p = 0.005), whereas prefrail participants showed no clear difference (β = -0.01; 95% CI, - 0.08 to 0.06; p = 0.797). Hypertension also showed an exploratory inverse relationship with EQ-5D index scores (β = -0.11; 95% CI, - 0.19 to - 0.02; p = 0.013).
conclusionsAmong long-term survivors, frail participants showed lower HRQoL scores, whereas prefrail participants showed no clear differences. Given the design, small frail subgroup, and survivorship bias, these findings should be interpreted as exploratory and hypothesis-generating.
