Inertial Head Accelerations in Front-On, One-on-One Tackles in Professional Women Rugby League Players.

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
backgroundRugby league tackles are a primary mechanism for head injuries, yet there is limited evidence on tackle-specific head kinematics in professional women's rugby league players.
objectivesWe aimed to identify factors that predict the ball carrier and the tackler inertial head kinematics in professional women rugby league players during self-selected, front-on, one-on-one tackles.
methodsNineteen professional women's rugby league players had their inertial head kinematics and the instantaneous resultant speed measured by a three-dimensional optoelectronic motion capture system during front-on, one-on-one tackles. Players were instructed to perform their own self-selected tackles over (i.e. 'smother' tackle) and under the ball (i.e. 'dominant' tackle) that they would use in-game. A generalised linear mixed model using a backward elimination method was used to predict peak inertial head kinematics.
resultsPeak resultant linear (g) and angular (deg/s
conclusionsTacklers should ensure their head alignment is positioned outside of the ball carrier's body to avoid direct body contact to reduce their risk of high inertial head kinematics. When coaches observe signs of whiplash-like mechanics, in a ball carrier during a tackle, they can use this visual cue to identify and then coach athletes how to brace better for impact. Caution is advised when considering a simplistic approach such as reducing tackle height to mitigate peak resultant head accelerations, as this strategy may reduce the impact on the ball carrier but increase the impact on the tackler.
