Function after Motor Vehicle Accidents: A Prospective Study of Mild Head Injury and Posttraumatic Stress
Bibliographic record
Abstract
Relationships among mild traumatic brain injury (MTBI), posttraumatic stress (PTS), and function were examined in 99 motor vehicle accident (MVA) admissions: 64 in an MTBI group and 35 in a no-MTBI comparison group. Assessments occurred within the first month and at 6 to 9 months. At follow-up, the sample was moderately disabled on the Sickness Impact Profile (SIP), 71% satisfied on the Reintegration of Normal Living Index (RNL), and 42% had returned to work. Only the SIP Psychosocial score was significantly different for MTBI groups; 24% of the sample showed definite symptoms of PTS. This group was significantly more disabled on the SIP, less satisfied on the RNL, and less likely to return to work. The proportion of variance in outcome explained in each model ranged from 32% (Physical SIP) to 44% (RNL). Results suggest the need for clinicians to be more aware of the strong influence of PTS on functional outcomes.

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.
