Whole and refined grains consumption and social interaction in children: a cross-sectional study.
Article in BMC nutrition, 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
backgroundSocial interaction is fundamental to a child's mental health and development. While diet is a known modulator of brain function, the specific roles of refined versus whole grain intake on social behaviors in children are not well understood. This study aimed to investigate association between refined and whole grain consumption and social interaction scores among Iranian children.
methodsThis cross-sectional study recruited 313 children aged 7-13 years from Kashan, Iran. Dietary intake was assessed using a validated 168-item food frequency questionnaire (FFQ). Social interaction was evaluated using the 40-item Social Communication Questionnaire (SCQ), where higher scores indicate greater difficulties with communication. Multivariable linear regression models were used to assess association between grain intake and SCQ scores, adjusting for a comprehensive set of demographics, socioeconomic, anthropometric, and dietary confounders.
resultsIn the fully adjusted model, total refined grains intake was significantly associated with higher SCQ scores (β: 0.007, 95% CI: 0.005, 0.009; P < 0.001). Conversely, total whole grain was associated with lower SCQ scores (β: -0.006, 95% CI: -0.009, -0.002; P < 0.001).
conclusionIn this study, higher intake of refined grains was associated with poorer social interaction, while greater consumption of whole grains was associated with more favorable social behaviors in Iranian children. Future longitudinal and interventional studies are required to clarify the causal relationship between grain quality and social interaction in children of different countries.
