Three-Year Outcome Following Moderate-to-Severe TBI in U.S. Military Service Members: A Descriptive Cross-Sectional Study
Bibliographic record
Abstract
This study examined the prospective course of neurobehavioral symptom reporting and health-related quality of life within the first 3 years following moderate-to-severe traumatic brain injury (TBI). Participants were 52 U.S. service members who were evaluated following a moderate-to-severe TBI sustained in the combat theater during Operations Iraqi and Enduring Freedom (90.4%), or from other noncombat-related incidents. Participants completed the Neurobehavioral Symptom Inventory and Post-Traumatic Stress Disorder-Checklist within 3 months postinjury, and at least one follow-up telephone interview at 12 (n = 27), 24 (n = 31), or 36 months (n = 22) postinjury. Approximately half of the sample (41.9%-63.0%) reported "persistent" symptoms from baseline to follow-up. A substantial minority also "improved" (22.2%-31.8%) or "developed" new symptoms (3.7%-16.1%). Ongoing physical and mental health problems were also reported. The number of service members receiving mental health treatment significantly reduced between 12 and 36 months postinjury (48.1%-18.2%), while complaints of bodily pain significantly increased (40.7%-68.2%). Despite ongoing symptom reporting, few reported suicidal/homicidal ideation (6.5%-9.1%), and a substantial majority reported good/excellent health status (74.1%-90.9%) and satisfaction with their life (81.5%-90.9%). Continued support and care for all service members who sustain a combat-related moderate-to-severe TBI is recommended, regardless of the presence or absence of symptom reporting within the first few months postinjury.

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.
