Understanding the relationship between child stimulation and brain function using neuroimaging techniques and behavioral measures: a study protocol.
Article in BMC psychology, 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
backgroundCognitively stimulating environments are known to promote the intellectual, socio-emotional and language development of children. Little is known about the relation between cognition and brain structure in young children in low- and middle-income countries (LMICs), particularly in sub-Saharan Africa (SSA) where children are at risk of developmental delay. The overall objective of this study is to measure the association between child stimulation and brain function using neuroimaging techniques and neuropsychological measures.
methodsThe study will employ an observational follow-up design using a mixed-methods approach. Caregiver-child interaction profiles, children's developmental scores (N = 980 children) and low-field magnetic resonance imaging (MRI) data (n = 343 children) will be analyzed to understand the relationship between stimulation, developmental outcomes, and brain structure. Associations among the various outcomes will be examined using univariable and multivariable linear regression adjusting for potential confounding factors.
conclusionThe findings are expected to provide evidence on the association of the quality, extent and frequency of caregiver-child interactions (child stimulation) and child development with brain structure. The evidence generated will inform policy and practice in the childcare sector. Support, investments or revision of policies and practices will be needed to strengthen the quality of childcare in center-based care.
