Distal-to-proximal progression of apophyseal injuries with age in male youth academy footballers: a two-season prospective cohort study of 16,024 player-seasons.
Article in British journal of sports medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
objectivesYouth football players are vulnerable to apophyseal injuries, which can have long-term consequences for health and performance. The objective was to assess the incidence, severity and burden of apophyseal injuries among U9-U21 academy football players over two seasons.
methodsTime-loss injuries and match/training exposure were tracked in male academy football players (U9-U21) from Premier League and Category One Academies. Apophyseal injuries were identified in a cohort of 16 024 player-seasons using Orchard Sports Injury Classification System (OSICS) codes, and their incidence, severity and burden were analysed.
resultsA total of 10 589 injuries were reported, including 603 apophyseal injuries. These injuries followed a distal-to-proximal progression with age, occurring most frequently in the ankle/foot in younger players (U9, U10 and U11), followed by the knee (U12) and hip/groin in older players (U15, U16 and U18). Across all player phases (U9-U21), injury burden (days/1000 hours) was higher in the hip/groin (3.5) and knee (3.4), compared with the ankle/foot (2.2) and pelvis/sacrum (1.4), with the highest apophyseal incidence (~0.4 injuries/1000 hours) and burden (~20 days/1000 hours) observed in the U12-U16 group, regardless of injury location. A significant trend of increasing injury severity (median days) was observed with age: U9-U11 (20), U12-U14 (29), U15-U16 (38) and U18-U21 (35).
conclusionsApophyseal injuries exhibit a distal-to-proximal progression with age, with the highest injury burden observed at the hip/groin and knee regions and in the U12-U16 group. These findings can help inform injury mitigation strategies adopted in youth academy football.
