Early physical activity after concussion is associated with sleep quality but not dizziness among adolescent athletes.
Article in Journal of science and medicine in sport, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
objectivesTo assess the association between early physical activity and post-concussion sleep quality, dizziness, and postural stability among adolescents with concussion compared to uninjured controls.
designCross-sectional.
methodsAdolescents ages 13-18 years assessed within 14 days post-concussion and uninjured controls. Those with concussion reported if they participated in physical activity between the concussion and assessment. Participants completed the Dizziness Handicap Inventory, Pittsburgh Sleep Quality Index, and single/dual-task tandem gait.
resultsWe enrolled 34 participants with concussion (early physical activity: n = 10, age = 15.8 ± 1.6 years, 70% female; no physical activity: n = 24, age = 16.0 ± 1.3 years, 50% female) and 21 uninjured controls (age = 16.0 ± 1.8 years, 48% female). Compared to controls, the no physical activity group reported worse sleep quality (Pittsburgh Sleep Quality Index: 3.8 ± 2.7 vs 8.0 ± 4.9 points, p = 0.002) and single-task tandem gait time (13.7 ± 3.4 vs 21.2 ± 8.1 s, p = 0.0006), while the early physical activity group did not (Pittsburgh Sleep Quality Index: 3.8 ± 2.7 vs 5.8 ± 3.2 points, p = 0.38; single-task tandem gait: 13.7 ± 3.4 vs 19.0 ± 5.7 s, p = 0.08). Compared to controls, early/no physical activity groups reported worse dizziness (Dizziness Handicap Inventory: 2.0 ± 3.4 vs 22.9 ± 23.8 vs 27.4 ± 19.2 points, p < 0.0001). There were no significant between-group differences for dual-task tandem gait (24.1 ± 8.0 vs 24.8 ± 6.2 vs 26.6 ± 7.3 s, p = 0.57).
conclusionsThe no physical activity group reported worse sleep quality and slower single-task tandem gait than controls, while both groups reported similar sleep quality and tandem gait. Early physical activity may promote sleep quality and postural stability, or early physical activity may be a function of improved sleep and postural stability after concussion.
