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
objectiveTo identify the key behavioural determinants that influence dietary self-management among adults with CKD, using the Theoretical Domains Framework and Behaviour Change Wheel to guide development of practical dietary interventions for clinical practice and research trials.
methodsA theory-informed secondary analysis of a published qualitative meta-synthesis that included 92 studies and 2924 adults with CKD from 23 countries. Themes from the meta-synthesis were mapped to Theoretical Domains Framework (v2) and linked to Behaviour Change Wheel intervention functions and behaviour change techniques. Potential behaviour change intervention strategies were then evaluated using the APEASE criteria (Affordability, Practicability, Effectiveness/Cost-effectiveness, Acceptability, Side-effects/Safety, Equity).
resultsTwelve of the 14 Theoretical Domains Framework (v2) domains were identified, indicating that dietary self-management in CKD is influenced by a broad range of cognitive, emotional, social, and environmental factors. Key barriers included inconsistent or conflicting dietary advice (Knowledge; Environmental Context and Resources), limited practical guidance (Skills; Behavioural Regulation), and emotional distress and social disruption associated with dietary change (Emotion; Social Influences). Trust in healthcare professionals and experiential learning also shaped adherence (Beliefs about Capabilities and Consequences). Optimism and Intentions domains were not evident. Mapping to the Behaviour Change Wheel identified Education, Enablement, Environmental Restructuring, Training, Persuasion, Incentivisation, and Modelling as relevant intervention functions. APEASE assessment suggested that Education and Enablement were the most feasible, acceptable, and scalable approaches for clinical implementation, while more complex components requiring additional resources or coordination (e.g., training and system-level changes) were comparatively less practical.
conclusionsDietary self-management in CKD is influenced by multiple behavioural determinants beyond knowledge alone. Interventions should therefore integrate education with skills training, confidence building, social support, and environmental adaptation. Embedding these multi-component strategies within clinical nutrition practice and research may enhance self-management and improve patient engagement across the CKD care pathway.
