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

Objective: To compare incidence rates (IR) of bodychecking (BC), head contacts (HC), and suspected injuries across Canadian adolescent ice sports (girls' ice hockey, ringette, boys' ice hockey, and para ice hockey) via a cross-sectional video-analysis study. Methods: Video-recordings were obtained from 144 games played between 2008 and 2022 (2021-2022 for ringette, girls', and para ice hockey; 2008-2021 for boys' ice hockey) in Canadian arenas. Video-recordings were analyzed using Dartfish video-analysis software to compare all ice sports. Univariate Poisson regression analyses (adjusted for cluster by team, offset by game-minutes) were used to estimate BC, HC, and suspected injury IRs and incidence rate ratios (IRRs) to compare rates across sports. Proportions of BCs and direct HC (HC Results: Compared with non-elite non-BC boys' ice hockey, there were significantly higher rates of BC in non-BC girls' ice hockey (IRR = 2.67, 95%CI: 1.82-3.90), non-BC ringette (IRR = 5.72, 95%CI: 4.03-8.11), and BC-permitted boys' ice hockey (IRR Conclusions: The high rates of BC are concerning in ice sports prohibiting BC (ringette and girls' ice hockey). The low proportion of penalized HCs across all ice sports suggests a need for improved policy enforcement to prevent injuries and concussions.
