1 · What the graph read from it

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.

2 · The registry

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

Objectives: This observational study compared incidence and characteristics of head impact events in matches in male youth under-18 football within Australia and India, to the Men's FIFA World Cup™ (FWC). Methods: Ten match videos from Australia, India and the 2018 FWC (total n ​= ​30) were coded for head impact events (purposeful headers and unintentional head impacts), match result as well as incidence rates (IR) per 1000 match-hours for heading performance characteristics. One-Way ANOVAs were conducted to assess statistical significance of heading IR and other characteristics. Results: Purposeful headers (n ​= ​2734) were the most common head impact event (97%) with significantly more headers being completed by players from India (IR:3239) compared to Australia (IR: 2096) and FWC (IR: 2509). Most headers were completed during free play, via contact with the players forehead. Heading duels were more common in FWC matches (32%), than those in Australia (23%) or India (19%) (p ​< ​0.001). More headers occurred in the centre of the pitch (range 36-48%), with centre-backs completing the most headers across all groups (range 30-33%). Winning teams in India performed more headers from set-pieces than losing teams (p ​< ​0.001). In FWC matches, winning teams performed more headers in the defensive third compared to losing teams (p ​= ​0.02). Conclusion: Despite similar heading characteristics across both U18 groups and the FWC, players in India recorded higher heading incidence, suggesting that heading guidelines would benefit from being country and age specific.
