Renaclic for Chronic Kidney Disease Self-Management: Formative User-Centered Co-Design Study.
Article in JMIR formative research, 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
Background: Chronic kidney disease (CKD) affects over 850 million individuals worldwide and requires sustained patient education, shared decision-making, and self-management support. Digital health platforms may facilitate these needs; however, many lack comprehensive, user-centered design and fail to address practical and psychosocial patient concerns. Objective: This study aimed to describe the formative co-design of Renaclic, a digital platform developed with patients and health care professionals (HCPs) to support CKD education and self-management in the French health care context. Methods: A three-stage user-centered design (UCD) study was conducted between April and August 2021. Stage 1 included benchmarking of 10 French-language CKD platforms and semistructured interviews with 8 stakeholders (3 HCPs: 1 nephrologist, 1 general practitioner, 1 nurse; 5 patients: 2 novice and 3 expert users). Stage 2 consisted of two virtual co-design focus groups incorporating card-sorting and interface design activities. Stage 3 translated identified needs into structured content categories and a low-fidelity prototype. Qualitative data were analyzed thematically. Results: Benchmarking revealed fragmented educational content, limited practical guidance on home dialysis logistics, insufficient coverage of lifestyle and psychosocial concerns, and minimal interactive features. Interviews identified five main themes: need for reliable centralized information, anxiety during care transitions, demand for practical lifestyle guidance, importance of reassuring language, and value of moderated peer exchange. More than 30 thematic content items were generated and organized through card-sorting into five consolidated content categories that structured the platform's information architecture. Co-design sessions informed mobile accessibility, simplified navigation pathways, and integration of educational, symptom-tracking, and community-oriented functionalities. Conclusions: This formative study demonstrates how participatory UCD with diverse CKD stakeholders can generate a structured, context-sensitive digital platform framework. Renaclic provides a replicable model for early-stage co-design of digital health interventions in chronic disease management. Future research will evaluate usability, engagement, and implementation in real-world settings.
