Epidemiology of injuries in male and female youth football players: A systematic review and meta-analysis

Fig. 1. Flow chart of the selection of studies for the meta-analysis. a No injury definition (n = 2), full-text not available (n = 2), and incidence for football players reported jointly with other sports (n = 1). ED = emergency departments.

Fig. 2. Training injury incidence in male youth football players, with 95%CI. a, b, c, d, e, and f indicate different cohorts in the same study. 95%CI = 95% confidence interval.

Fig. 3. Match injury incidence in male youth football players, with 95%CI. a, b, c, d, e, and f indicate different cohorts in the same study. 95%CI = 95% confidence interval.

Fig. 4. Training injury incidence in female youth football players, with 95%CI. g, h, and i indicate different cohorts in the same study. 95%CI = 95% confidence interval.

Fig. 5. Match injury incidence in female youth football players, with 95%CI. g, h, and i indicate different cohorts in the same study. 95%CI = 95% confidence interval.

Fig. 6. Location of injuries in male (left side) and female (right side) youth football players. The upper boxes (with solid lines extending from them) represent the incidence of injury for main groups (head and neck, upper limbs, trunk, lower limbs), whereas the lower boxes (with dashed lines extending from them) represent the incidence of injury for lower extremities categories (hip/groin, thigh, knee, lower leg/Achilles tendon, ankle, foot/toe).
