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

Background: It is not well understood how tackling technique influences the inertial head kinematics of a tackler or ball carrier. This study identified the modifiable components of the tackler's technique (including instantaneous speed at contact) that predicted inertial head kinematics of a male tackler and ball carrier during a front-on, one-on-one, 'slow speed' rugby tackle. Methods: Three-dimensional motion capture recorded 455 torso tackles across 15 rugby players. Principal component analysis identified four significant tackle related variables: Results: The ball carrier's instantaneous speed at contact, not the tackler, predicts inertial head kinematics of the tackler's and ball carrier's inertial head kinematics (p ​< ​0.05). Tacklers that adopt a more Conclusion: To reduce the tackler's peak inertial head kinematics, the tackler could adopt a tackle strategy that looks upwards (i.e., not looking to the ground) and adopts partially bent-at-waist (i.e., is not upright) and avoids a kyphotic posture or tilting their pelvis forward to primarily flex their hips to lower their body height. Clinical trial registration: This is not a clinical trial.
