Quantifying differences in head kinematics associated with tackle form in youth football.
Article in Journal of sports sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
American football has a high rate of concussion and subconcussive head impacts resulting from tackling collisions. A tackle must be properly executed to maximize safety for involved athletes. The study objective was to develop a grading rubric and evaluate the relationship between tackle form and head kinematics in youth football. A grading rubric was co-developed with stakeholders and informed by standards for tackling. Head kinematic data were collected from 14 youth athletes via instrumented mouthpiece. Mixed-effects models, linear regression, and least absolute shrinkage and selection operator (LASSO) analysis was used to examine the data. A total of 149 head acceleration events (HAEs) that occurred across 125 tackles were collected. The median [95th percentile] peak linear acceleration (PLA), rotational acceleration (PRA), and rotational velocity (PRV) measured from tackling HAEs were 12.9 g [31.2 g], 927 rad/s
