Effects of a Dialogic Book-sharing Intervention for Female Caregivers in Rural Tanzania (EDBiT): Protocol for a Randomized Controlled Trial.
Article in JMIR research protocols, 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
backgroundChildren in low- and middle-income countries face obstacles to optimal language and cognitive development due to a variety of factors related to adverse socioeconomic conditions. One of these factors is compromised caregiver-child interactions and associated pressures on parenting. Early development interventions, such as dialogic book-sharing (DBS), address this variable, with evidence from both high-income countries and urban areas of low- and middle-income countries showing that such interventions enhance caregiver-child interaction and the associated benefits for child cognitive and socioemotional development. Yet, evidence for DBS effects is lacking from poor rural communities where the need for such early development intervention may be greatest.
objectiveThe objective of this study is to assess the effects of a DBS intervention, a parenting program for female caregivers of children aged between 15 and 45 months, implemented in rural Tanzania. We aim to assess the impact of the intervention on the following domains: child cognitive and socioemotional skills, parenting and parental stress, and child health.
methodsThe study is a 3-arm cluster randomized controlled trial. In total, 443 female caregivers participated in the study. Clusters of caregivers were randomized to either (1) an index DBS intervention group, (2) a playful activity active control group, or (3) a waitlist control group. The active control group was designed to control for any attention effects, ensuring that observed improvement in the index group can be attributed to the DBS intervention's content. The primary outcomes were child language, parental sensitivity, and parent-child interaction. The secondary outcomes concerned child attention and behavior, parenting practices, and parental stress. A combination of questionnaires and direct observations was applied. Qualitative methods were also used, primarily to capture caregivers' experiences and subjective perspectives on intervention-induced changes.
resultsData collection for the study was completed in September 2024. The study results are expected to be published by late 2025.
conclusionsThis randomized controlled trial of a DBS intervention implemented in rural Tanzania adds to a growing body of international literature exploring the impact and limitations of a simple and scalable early development intervention to enhance child outcomes.
