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
Objective: This study aimed to investigate the factors influencing self-care among older patients with heart failure (HF) and their spouses from a dyadic perspective. Methods: An explanatory sequential mixed-methods design was employed. In the quantitative phase, 145 dyads of older HF patients and their spouses were recruited from a tertiary hospital in Zhejiang, China. Validated instruments were used to measure patient self-care, spouse contribution to self-care, disease-specific health literacy, mutuality, and social support. Multiple linear regression and the Actor-Partner Interdependence Model (APIM) were conducted separately for three self-care subscales (maintenance, management, confidence). In the qualitative phase, 10 dyads were purposively sampled for one-to-one semi-structured interviews, and data were analyzed via Colaizzi's phenomenological method. Quantitative and qualitative findings were integrated adhering to the Theory of Dyadic Illness Management (TDIM). Results: Both patients and spouses scored below the 70-point adequacy threshold across all three self-care subscales. APIM revealed significant actor effects of health literacy and mutuality on self-care for both dyad members. Significant partner effects were observed in two dimensions: spouse mutuality was positively associated with patient self-care maintenance ( Conclusion: Health literacy and mutuality are core correlates of self-care among older Chinese HF patient-spouse dyads, with dimension-specific dyadic interaction patterns. Clinical interventions should develop tailored dyadic support strategies for distinct self-care dimensions, and pay attention to optimizing age-friendly digital healthcare services and improving caregiving culture. This study provides exploratory evidence for context-specific extension of the TDIM framework.
