Factors influencing patient involvement in treatment decision-making for diabetic retinopathy: a mixed methods study protocol.
Article in BMJ open, 2026. 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
introductionThe diversity of treatment options for diabetic retinopathy (DR) and the high uncertainty about the benefits and risks of different treatment modalities necessitate shared decision-making between patients and healthcare professionals. However, little is known about the involvement of individuals with DR in treatment decision-making in China. This study aims to gain insight into the current status and factors associated with involvement in treatment decision-making in patients with DR. Furthermore, we will explore the experiences and perceptions of patients with DR regarding their involvement in treatment decision-making. METHODS AND ANALYSIS: We will conduct a mixed-method study using an explanatory sequential design. In the quantitative research (n=350), participants' actual decision-making roles, sociodemographic data, disease-related data, health literacy, need for involvement in decision-making, decision-making self-efficacy, social support and ophthalmologist facilitation of patient involvement will be investigated to analyse the current state of patient involvement in treatment decision-making and the factors influencing it. Descriptive statistics, one-way analysis of variance and multinomial logistic regression will be performed. During this period, individual semistructured interviews will be conducted with a subset of these participants to understand the perceptions and experiences of people with DR regarding their involvement in treatment decision-making, and thematic analysis will be used to analyse the interview data. Finally, the joint display will be used to integrate quantitative and qualitative data. ETHICS AND DISSEMINATION: Ethical approval for this study has been obtained from the Ethical Review Committee for Human Trials of Shanghai General Hospital, China (number: 2024-098). Written informed consent will be obtained from all participants after they have been fully informed about the study, prior to any data collection. The study's findings will be disseminated through peer-reviewed publications and conference reports. TRIAL REGISTRATION NUMBER: ChiCTR2400087906.
