Sex-based differences in running performance among children aged 7-9 years in new South Wales track competition.
Article in JSAMS plus, 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
Background: Recent research has shown that prepubertal males outperform females in running competitions; however, prior studies have focused on distances of 100-1600 m and most have relied on U.S.-based data. This study evaluated sex-based differences in running performance among under-8, under-9, and under-10 athletes in 70 m, 100 m, 200 m, and 400 m races at the 2024 Little Athletics New South Wales (NSW) Regional Track & Field Championships in Australia. Methods: Official race times for all competitors ( Results: Males ran significantly faster than females across all events and age groups ( Conclusions: These findings confirm previously reported male performance advantages in prepubertal children and extend the evidence to a shorter sprint distance (70 m) and to Australian data. Notably, between-sex performance differences were more than twice as large as the variability within sex among comparably placed finishers. These results may help inform research and practice on youth sport talent identification and development.
