Blood-based biomarkers suggest prolonged axonal Injury following pediatric mild traumatic brain injury.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Pediatric mild traumatic brain injury (pmTBI) affects millions of youth annually but underlying pathophysiology and time for physiological recovery remains unknown. Non-fasting plasma samples were obtained in 59 pmTBI (28 females; age 14.9 ± 2.7) at approximately 7 days and 4 months post-injury and in 41 matched healthy controls (HC: 20 females; age 14.3 ± 2.8). Samples were analyzed for GFAP, NFL, Tau, pTau181 and UCH-L1 protein concentrations in conjunction with a clinical battery. Significant effects of diagnosis (pmTBI > HC) existed at ~ 7 days (p < 0.001; Cohen's d = 0.72) and ~ 4 months (p = 0.015; Cohen's d = 0.41) post-injury for NFL. NFL was also elevated in pmTBI with significant alterations to mental status (e.g., post-traumatic amnesia) relative to patients without (p = 0.014; Cohen's d = 0.77). UCH-L1, GFAP and pTau181 did not differ between groups, but demonstrated negative associations with days post-injury (small to medium effect sizes) suggestive of a more rapid release/clearance. Post-concussive symptoms had the best diagnostic classification accuracy at ~ 7 days, but NFL ranked higher at 4 months post-injury. Preliminary findings highlight dynamic fluctuations in blood-based biomarkers in the first week of pmTBI, with ongoing evidence of protein release (NFL) at 4 months. NFL demonstrated additional promise for delineating injury severity within the spectrum of pmTBI.
