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 translate the Caregiver Contribution to Self-Care of Coronary Heart Disease Inventory, version 3a (CC-SC-CHDI v3a), into Chinese and evaluate its psychometric properties after cultural adaptation. Methods: Between December 2024 and April 2025, a cross-sectional survey was conducted with 278 primary caregivers of patients with coronary heart disease, recruited from cardiology departments in two hospitals in Dalian, China. Translation was based on the Brislin model, which involved forward-backward translation, expert panel assessment, and a pilot test with 30 caregivers. Psychometric evaluation included item analysis, assessment of content validity, convergent validity, concurrent validity, and confirmatory factor analysis (CFA). Reliability was assessed through internal consistency (Cronbach's Results: The Chinese version of the CC-SC-CHDI v3a demonstrated high content validity, with item-level CVI values ranging from 0.90 to 1.00 and scale-level CVI values between 0.97 and 1.00. All items had critical ratios exceeding 3.0 and item-total correlations above 0.4. CFA results indicated a satisfactory model fit ( Conclusion: The culturally adapted Chinese version of the CC-SC-CHDI v3a is a reliable and valid tool for assessing caregiver contributions to self-care in Chinese patients with coronary heart disease.
