Effects of body mass index and extracurricular sports activities on physical fitness in school-aged children.
Article in Frontiers in public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background: We are seeing a steady decline in children's physical fitness. Along with overweight and obesity, low physical fitness is one of the most serious disorders in child development. One solution to these problems is additional physical activity. It was investigated whether reduced physical fitness is associated with an increased body mass index and whether children who participate in extra-curricular sports activities have better physical fitness. Methods: The study involved 201 children (101 girls, 100 boys) aged 10 ± 2 (grades 1-8 of the primary school). Half of the participants reported participating in extra-curricular sports activities, while half did not participate in any sports activities. The children were assessed for body mass index, grip strength, balance, strength, speed and reaction time. Results: Significant differences in fitness test results were observed between active and inactive students. Significant differences were also found between students with different body mass index. The 4 months of schooling had a positive effect on most of the fitness characteristics assessed. Grip strength appeared to be a determinant of the other fitness scores. Conclusion: The hypotheses that both additional physical activity and BMI will influence children's fitness, and that 4 months of schooling will have a positive effect on improving students' fitness, were confirmed. Hand-grip strength was found to be a determinant of better performance in almost all other fitness tests.
