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: Patients with end-stage heart failure (ESHF) face high mortality and complex decision-making needs, yet advance care planning (ACP) acceptance is insufficient in clinical practice. This study aimed to explore factors influencing ACP acceptance among ESHF patients based on the COM-B model, focusing on knowledge deficits, familism, filial piety, and death taboo, to provide evidence for developing culturally adapted ACP interventions in China. Methods: A descriptive phenomenological qualitative design was used. Twenty-two ESHF patients were recruited via purposive sampling from a tertiary hospital. Semi-structured in-depth interviews were guided by the COM-B framework. Data were analyzed using Colaizzi's seven-step phenomenological method for coding and theme extraction. Results: Three core themes and nine sub-themes were identified: (1) Capability: severe lack of disease and ACP knowledge, weak information comprehension and decision-making capacity, and limited information access; (2) Opportunity: family-centered decision-making restricting patient autonomy, filial piety leading to communication avoidance, inadequate medical communication, and cultural taboos causing moral pressure; (3) Motivation: fear triggered by death taboo, weakened autonomous motivation due to filial responsibility, and low perceived benefits of ACP. Conclusion: ACP acceptance among ESHF patients is shaped by cognitive capability, family culture, clinical support, and internal motivation. Insufficient knowledge is the fundamental barrier, and familism and filial piety act as key structural constraints. Culturally adapted interventions based on the COM-B model can effectively improve ACP acceptance and decision-making quality. The findings are transferable to ACP practice in other chronic conditions and collectivist cultural settings.
