Fluid Biomarkers of Pediatric Mild Traumatic Brain Injury: A Systematic Review
Bibliographic record
Abstract
Public concern is growing about the short- and long-term effects of pediatric mild traumatic brain injury (mTBI). This concern is amplified because pediatric mTBI has the potential to go undiagnosed in acute care settings, placing children at increased risk for reinjury prior to complete recovery. The management of mTBI can be particularly challenging due to the lack of validated biomarkers that clinicians can use to objectively diagnose pediatric mTBI, predict risk for prolonged recovery, or demonstrate mTBI recovery. Fluid-based biomarkers have drawn increased attention as an objective measure to diagnose and manage pediatric mTBI, but investigations of promising biomarkers may pose unique challenges in pediatric populations. Our systematic review confirms the relative paucity of high-quality, clinically impactful diagnostic or prognostic fluid biomarker studies, on samples representing only a small fraction of pediatric mTBI. Ultimately, well-designed longitudinal studies across diverse points of care are needed to truly characterize the utility of fluid biomarkers of injury and recovery for the pediatric mTBI patient.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
