Impact of shared storybook reading on child development: The Japan Environment and Children's Study.
Article in Pediatric 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
backgroundShared storybook reading in early childhood is crucial for cognitive and social development, but its association with broader developmental domains is less established. This study aimed to investigate the association between the frequency of shared storybook reading and overall child development.
methodsThis study analyzed data from the Japan Environment and Children's Study, a nationwide prospective birth cohort study. The frequency of shared storybook reading was assessed at multiple time points up to age 3. Child development was assessed using the Ages and Stages Questionnaire-3 (ASQ-3). The association was analyzed using multivariate models adjusted for parental background, opportunities to play with the child, and media exposure.
resultsA total of 36,866 mother-child pairs were analyzed. The frequency of storybook reading positively correlated with the ASQ-3 scores across all developmental domains. After adjustments, frequent reading at age 3 was associated with a 5.5-point increase (95% CI: 5.0-6.0, p < 0.001) in communication scores compared to rare reading. Among children whose ASQ-3 scores fell below the cutoff at the age of 1 year, more frequent reading at subsequent ages was associated with greater score improvements.
conclusionFrequent shared storybook reading positively correlated with the overall developmental progress in early childhood. IMPACT: Based on a large-scale nationwide birth cohort study, frequent shared storybook reading is positively associated with the overall developmental progress in early childhood. Even for children with developmental delays at age one, continuous reading was positively associated with their development.
