Hawaiian High School Football Player Positional Differences in Helmet Impact Characteristics.
Article in Journal of athletic training, 2024. 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
contextThe importance of analyzing head impact exposure among football players is well established, yet few studies have explored the differences across position groups in high school athletes. Better understanding of these differences may provide optimized intervention strategies for coaches and healthcare providers.
objectiveTo quantify the difference of head impacts per exposure (Imp/E) and impact burden high school football player position groups.
designProspective observational.
settingHigh school athletic fields during Fall sports seasons. PATIENTS AND
participants200 football players from three high school varsity teams including 69 offensive/defensive linemen, 51 linebackers/running backs/tight ends and 80 cornerbacks/safeties/wide receivers (16.1±0.9yrs, 177.9±7.8cm, 86.4±22.7) categorized as linemen, backers, and skills players respectively.
main outcome measuresImp/E across positions, teams, session type, and seasons. Cumulative head impact burden per location (front, top, right, left, back) across position groups.
resultsSignificant differences in Imp/E were found between position groups (P<0.001), where the backers group, (3.77[95% CI: 3.146, 4.395]) experienced higher total Imp/E compared to linemen (1.47[ 95% CI: 0.983, 1.96]) and skill players (1.56[95% CI: 1.11, 2.01]). Total accumulated burden of head impacts was significant (F(2,194) = 4.938, P<0.008), with backers (4622.85g's [95% CI: 3077.43, 6168.27]) significantly (P=0.011) higher than linemen (2657.70g's [95% CI: 2045.61, 3269.19 ]) and skill players (2875.7g's [95% CI: 2216.38, 3535.01]) (P=0.022). Front location impact burden (F(2, 194) = 7.784, P<0.001) revealed backers (1606.24g's [95% CI: 977.89, 2234.58]) also significantly (P=0.008) higher than both linemen (768.24g's [95% CI: 433.84, 1102.64]) and skill players (567.75g's [95% CI: 360.71, 774.78]) (P<0.001).
conclusionLinebackers, tight ends, and running backs experienced more Imp/E and higher cumulative burden than other positions, which highlights the potential influence of specific positional requirements during football participation. Coaches and healthcare providers should be aware that a position's role during play may directly relate to changes in head impact risk.
