Player ranking is associated with physical performance and body composition in 12-year-old female soccer players.

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: The relative contribution of biological maturation and body composition to performance in youth female soccer remains unclear. This study compared skeletal maturity, body composition, and physical performance across ranking groups in 12-year-old female players within a community club system. Methods: Eighty-eight players (11.9 ± 0.3 years) completed bone age (BA) assessment from non-dominant wrist radiographs, DXA body composition testing, and field-based measures including countermovement jump (CMJ), Illinois change-of-direction test with ball (ICODT-BALL), 40-m sprint, and Yo-Yo intermittent recovery test level 1 (IR1). Players were assigned by their coaches to three performance-based ranking groups. Between-group differences were analysed using one-way ANOVA with Results: BA did not differ significantly between ranking groups ( Conclusion: Performance ranking at chronological age 12 primarily reflects agility performance with the ball, 40-m sprint performance and CMJ height, but not biological bone age. Higher-ranked players also demonstrated lower Fat%, whereas FFMI did not differ significantly between ranking groups.
