Association of healthy eating behaviours and comorbidity on quality of life among adults with beta-thalassemia major: a moderation analysis.
Article in Quality of life research : an international journal of quality of life aspects of treatment, care and rehabilitation, 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
purposeAdults with beta-thalassemia major (BTM) and comorbidities may experience poorer quality of life (QoL), while healthy diet are suggested to improve chronic disease management and health outcomes. The purpose of this study was to explore how healthy diet can impact QoL among adults with BTM, and whether healthy diet can buffer the impact of comorbidities on QoL of this population.
methodsCross-sectional data of 317 adults (18 years old or older) with BTM in Vietnam was analysed. Healthy eating scores was measured by Healthy Eating Scores-5 scale. Four domains of QoL (physical health, psychological, social relationships, and environment) were assessed using the 26-item Quality of Life scale (WHOQOL-BREF). Multivariable linear regression was used to assess the association of interest and its moderation between healthy eating scores and comorbidity status (yes/no).
resultsIndividuals with BTM and comorbidity had significantly a lower QoL score in physical health and social relationships domain than those without comorbidity. This association was inversely moderated by healthy eating scores, specifically in physical health, psychological, and environment domain. As individuals had higher scores in healthy eating, the difference in QoL scores in the three domains above between individuals with and without comorbidities reduced.
conclusionIndividuals with BTM and comorbidities have a poorer quality of life. However, encouraging a healthy diet could mitigate this risk. Healthcare system should include dietitians and family caregivers in chronic care management for patients with BTM.
