Results from the regression models for each motor competence outcome: associations between the activity composition and Dragon Challenge scores, stratified by sex and school type. Activity composition expressed as isometric log-ratio coordinates. Models adjusted for age (excluding stratified by school type analysis), sex (excluding stratified by sex analyses), BMI z-score, and IMD decile. Bolded estimates are significant at p < 0.05 (‘school’ as the single, random intercept to account for nesting)
Χ² chi-squared values that are generated by the statistical model (mixed effects)
