Exploring Patient Involvement in Treatment Decision-Making for Diabetic Retinopathy: A COM-B Model-Based Cross-Sectional Survey.
Article in Patient preference and adherence, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Patient involvement in treatment decision-making has increasingly been emphasized in the healthcare system. However, research on patient involvement in treatment decision-making for diabetic retinopathy (DR) remains scarce in China. Guided by the Capability-Opportunity-Motivation-Behavior (COM-B) model, this study aimed to explore the current status and influencing factors of patient involvement in treatment decision-making for DR. Methods: This cross-sectional study recruited 336 patients with DR by convenience sampling from a tertiary hospital in Shanghai, China. The All Aspects of Health Literacy Scale (AAHLS), Social Support Rating Scale (SSRS), Facilitation of Patient Involvement Scale (FPIS), Decision Self-Efficacy Scale (DSES), and Patient Expectation for Participation in Medical Decision-making Scale (PEPMDS) were used to evaluate health literacy, social support, ophthalmologist facilitation of patient involvement, decision self-efficacy, and need for decision-making involvement, respectively. The Control Preference Scale (CPS) was used to assess patients' actual involvement roles in treatment decision-making. Descriptive statistics, univariate, and unordered multinomial logistic regression analyses were conducted. Results: Among the 336 patients with DR, 21.1% reported an active role, 30.7% a collaborative role, and 48.2% a passive role. Compared to passive roles, younger age, higher income, lower ophthalmologist facilitation, and higher need for deliberation were associated with a higher likelihood of adopting active roles; higher income, greater critical health literacy, higher ophthalmologist facilitation, and higher need for deliberation increased the likelihood of adopting collaborative roles. Compared to active roles, collaborative roles were significantly associated with older age, higher objective support, and higher ophthalmologist facilitation. Conclusion: This study demonstrates that passive involvement remains the predominant decision-making role among DR patients in China. Promoting patient involvement in decision-making is therefore imperative and calls for strategies that enhance health literacy, strengthen ophthalmologist facilitation and objective support, and address the need for deliberation. Future research could develop and evaluate integrated interventions informed by these COM-B components.
