Effect of the 'digital plus' approach to upscaling early childhood development services in rural China: study protocol for a cluster randomised controlled trial.
Article in BMJ open, 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
introductionThe high prevalence of developmental delays among young children poses significant barriers to long-term social mobility in low-income and middle-income countries. Digital interventions aimed at early childhood development (ECD) have shown promise in improving developmental outcomes, yet scalable and effective strategies remain under-explored. This study aims to evaluate the effectiveness of a digitally delivered parenting intervention to improve early child development in rural China. METHOD AND ANALYSIS: We design a parallel cluster-randomised controlled trial to evaluate a 12-month digitally delivered ECD intervention in rural China. Key inclusion criteria are households with children aged 6-24 months and without relocation intentions. Key exclusion criteria are children with a severe disability. Participants are masked to treatment assignment. The project implements village-level interventions in three counties in central China, involving 70 villages (clusters). Implementation involves two phases: the preparatory phase and the online phase, in which 'Parenting the Future' curriculum will be delivered through a newly developed mobile application. During the preparatory phase, county-level parenting trainers will conduct weekly home visits to each sampled household. In the online phase, caregivers will primarily access weekly parenting training through prerecorded videos on a mobile application. Trainers will conduct short, fortnightly home visits to manage toys and picture books loaned through the same application in accordance with the training. The planned total treatment involves 48 sessions over 1 year. Assessments were conducted via home visits at baseline and endline. The primary outcomes include cognitive development measured with the Bayley Scales of Infant and Toddler Development, third edition and social-emotional development measured with the age and stage questionnaire: social emotional. Secondary outcomes include caregiver engagement and the home learning environment measured by family care indicators and responsive caregiving rating scale. The trial aims to test the effectiveness and scalability of a hybrid ECD intervention. ETHICS AND DISSEMINATION: Ethical approval for this study has been obtained from the Institutional Review Board of Southwestern University of Finance and Economics. Informed consent will be obtained from all participants, with appropriate measures in place to ensure participant confidentiality. Results from the study will be shared through academic publications, policy briefs and presentations to government stakeholders and international organisations, contributing to policy discussions on the scalability of digital ECD interventions. TRIAL REGISTRATION NUMBER: AEA RCT Registry (AEARCTR-0013908); ISRCTN Registry (ISRCTN15854033).
