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 the association between tackle characteristics and suspected concussion among Canadian high school girls' rugby union players. Methods: A case-control video-analysis study was used to examine the association between a priori tackle characteristics (eg, type, height, head position) and suspected concussion. For every concussive tackle event, six non-concussive tackle events were matched for game and team. Penalised logistic regression was used to estimate ORs with 95% CIs for concussion given tackle characteristics. Results: 33 concussive tackle events, including 38 concussions, were identified. 20 were ball carrier concussions (53%). 261 (228 non-concussive, 33 concussive) tackle events, including 632 individual tackler and ball carrier instances, were coded. All ball carrier head contact intensity types were associated with concussion compared with no head contact. A trip tackle type (OR: 4.41, 95% CI 1.25 to 15.61), illegal tackle type (OR: 4.41, 95% CI 2.67 to 7.29), deceleration (OR: 14.03, 95% CI 4.65 to 42.30) and no change of speed (OR: 18.81, 95% CI 10.04 to 35.24) increased concussion odds for ball carriers. A tap (OR: 10.64, 95% CI 2.00 to 56.62) and trip tackle type (OR: 5.91, 95% CI 3.18 to 10.99), two (OR: 3.38, 95% CI 1.13 to 10.07) or three (OR: 13.91, 95% CI 1.74 to 111.53) tacklers within the event, and a head-down position (OR: 40.54, 95% CI 27.78 to 59.18) increased concussion odds for tacklers. Higher tackler contact on ball carrier (tackle height) increased concussion odds for ball carrier (reference: knee-to-upper-leg; waist-to-sternum OR: 2.27, 95% CI 1.08 to 4.80; sternum-to-armpit OR: 5.65, 95% CI 1.40 to 22.87) and tacklers (sternum-to-armpit OR: 4.20, 95% CI 1.26 to 14.03). Conclusion: Numerous tackle characteristics were associated with ball carrier and tackler concussion. This is the first study to identify tackle height on ball carrier as a risk factor for concussion in girls' rugby. Future directions should consider tackle training programmes and lower tackle height as potential concussion prevention solutions.
