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: To evaluate physical contact (PC), head contact (HC) and suspected injury incidence rates (IR) in youth ringette players across different age groups and levels of play, using video analysis. Methods: This is a cross-sectional video-analysis study of competitive youth ringette games (regular season, provincial and national tournaments) filmed during the 2021-22 season in a major Canadian city. Participants included under 16 years of age (U16; ages 14-15 years) and under 19 years of age (U19; ages 16-18 years) ringette players competing at the A and AA levels (top two most elite levels). A total of 35 games were analysed representing 3256 team-minutes.Primary outcomes included the IRs of bodychecking (illegal trunk PC) and HCs (direct-HC Results: The bodychecking IR was 17.34/100 team-minutes (95% CI 14.80 to 20.33) and HC IR was 19.09/100 team-minutes (95% CI 16.74 to 21.78). Few bodychecks (29%) and HC Conclusion: High rates of bodychecking and HCs were found across all ages and levels of play, despite rules prohibiting these actions in ringette. Injury prevention efforts should target reducing bodychecking and HC behaviours to improve player safety.
