Associations Between Relative Age, Siblings, and Motor Competence in Children and Adolescents.
Article in Children (Basel, Switzerland), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
backgroundMotor competence is a key determinant of children's physical, cognitive, and social development, and it is influenced by various biological and environmental factors. Among these, relative age and the presence of siblings have been proposed as potential contributors, yet their impact remains underexplored, especially in school-aged populations.
objectiveThis study investigates the influence of relative age and the effects of the presence of siblings on the motor competence of children and adolescents.
methodsThe motor competence level of 747 students, 381 from primary school (mean age = 8.81 ± 1.8 years) and 366 from secondary school (mean age = 13.52 ± 1.22 years), was measured by the means of the Canadian Agility and Movement Skill Assessment. Participants were queried about their birth date and whether they had any older siblings.
resultsOverall, motor competence exhibited an upward trend with chronological age, reaching its peak among children aged 14 years old. Analysis revealed a significant impact of relative age effects on motor competence among primary children, with considerably higher scores in the first semester (
conclusionsThese findings suggest that physical education teachers should be aware of the influence of relative age not only when assessing motor competence but also when designing and implementing their teaching practice in primary school settings. In contrast, the effect of relative age appears to be less significant in secondary education, where it may be less relevant for both evaluation and teaching practice. Further research should explore longitudinal designs and consider additional psychosocial and environmental variables to better understand how these factors influence motor competence development over time.
