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
The current literature suggests that football (soccer) players' age and maturity status affect the likelihood of sustaining certain injuries; however, few studies have used indicators of sexual maturity. By retrospectively analysing prospectively collected data, we therefore aimed to describe injury patterns among young football players in a Spanish academy over three seasons and investigate associations with sexual maturity status. Participants included 354 male youth players aged 7 to 18, categorised into five age groups. Maturity assessments were conducted annually, utilising pubertal stages for genitalia and pubic hair, alongside testicular volume measurements. Time-loss injuries were recorded by medical staff and associations with pubertal stages were examined using Generalized Estimating Equations (GEE). Results indicated an overall incidence of 2.2 injuries per 1000 hours. Higher injury rates were observed for more advanced maturational stages (p < 0.05). Common injury types included muscle injuries (23%), joint sprains (20%), and growth-related injuries (16%), with specific injuries varying by maturity stage. For instance, growth-related injuries peaked during mid-puberty, while muscle and joint injuries were more frequent in advanced maturity stages (p < 0.05). Our findings suggest that sexual maturity status was significantly associated with injury occurrence in youth football. This emphasises the importance of understanding the interplay between biological maturity and injury occurrence. In addition to considering players' age or playing level, coaches and clinicians may consider tailoring training and injury prevention strategies according to players' maturity levels to better mitigate injury risks.
