A mobile app intervention to support nutrition education for heart failure management: co-design, development and user-testing.
Article in BMC nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 2 of them syntheses that pooled it.
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
backgroundMobile apps show promise in supporting patients with heart failure (HF) in adhering to dietary guidelines for sodium and fluid. Though numerous apps to support HF management exist, only a few have dedicated features to support dietary adherence.
objectivesTo describe the process and outcomes from the development and testing of Sodium Navigator
methodsBackground research in app development, behaviour change, nutrition and qualitative interviews with patients and healthcare providers informed app content and design. Weekly team meetings were held to establish learning objectives, content, and features of the app until a prototype was developed and approved by the research team. Using a quasi-experimental mixed-methods design, patients with HF (≥ 18 years) evaluated the prototype via one-on-one online user-testing sessions. App engagement, satisfaction, and usability were measured using a 12-question patient-reported Likert-scale questionnaire. Participant feedback on app content and features was gathered using qualitative interviews.
resultsSix educational modules (dietary sodium recommendations, contributors of sodium in the diet, nutrition labelling, lowering dietary sodium, fluid restriction and goal setting), ten behaviour change techniques (e.g., feedback on behaviour, social support) and gamified components (i.e., avatar, point-system) were integrated into the app. Participants with HF (n = 10, 56±15 years, 80% women) enjoyed using the app (90%), strongly agreed that the information was meaningful and useful for their general health (80%) and was easy to use (70%).
conclusionResults demonstrate the potential of Sodium Navigator
