Female sex, training volume and sleep amount are risk factors for sports-related injuries: a 1-year prospective cohort study on adolescent elite athletes.

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: There are limited studies regarding risk factors for sports-related injuries in adolescent athletes. Objectives: The primary aim was to identify risk factors for sustaining a sports-related injury among adolescent athletes during a follow-up of up to 1 year. A further aim was to investigate sex differences. Methods: Potential risk factors in adolescent elite athletes (n=171) were addressed through a baseline questionnaire. An injury was defined as any physical complaint resulting from competition or training, regardless of medical attention or time loss. The occurrence of new injuries was prospectively monitored during the following year using weekly questionnaires. χ Results: Female sex (OR 3.51, p=0.02) increased the injury risk. Training ≥9 sessions/week increased the risk in males (OR 3.98, p=0.03). Sleep amount ≥8 hours/night (OR 0.16, p=0.049) decreased the risk in females. Male athletes trained ≥9 sessions/week to a greater extent compared with female athletes (57% of males vs 30% of females (p<0.001)). The yearly injury prevalence for all athletes was 81%. Conclusions: Female sex is a risk factor for sports-related injuries in adolescent athletes, as well as low sleep amount in females and high weekly training volume in males. Adolescents are injury-prone, and further development and optimisation of programmes for injury prevention is crucial, especially in female adolescent athletes.
