Abstract
In Brief Study Design. Nonsystematic review and discussion of prognosis after whiplash injury. Objective. To summarize the research and identify a research agenda for improving prognostic models after whiplash injury. Summary of Background Data. With up to 50% of individuals failing to fully recover after whiplash injury, the capacity to determine a precise estimate of prognosis will be important. Systematic reviews note inconsistencies and shortcomings of research in this area. Methods. A nonsystematic review and discussion. Results. Most prognostic whiplash studies are phase 1 (exploratory) studies with few confirmatory or validation studies yet available. It is recognized that whiplash is a heterogeneous condition and clinicians require prognostic indicators for clinical use. Although the evidence is not sufficiently strong to make firm recommendations, there are some prognostic factors that have shown consistency across studies and could be considered as preliminary flags or guides to gauge patients potentially at risk of poor recovery. These include pain and/or disability levels, neck range of movement, cold and mechanical hyperalgesia and psychological factors of recovery beliefs/expectations, post-traumatic stress symptoms, depression, and pain catastrophizing. It is not known whether these factors can be modified or whether modification will improve outcomes, thus they should not be considered directives for management. Research priorities identified to develop improved predictive models include confirmation and validation of factors identified in phase 1 studies; investigation of the interaction between variables; investigation of the predictive value of changes in variables over time; the inclusion of validated outcomes including measures of pain and disability as well as perceived recovery and psychological outcomes. Conclusion. The current evidence is not sufficiently robust to be able to confidently predict outcome after whiplash injury. A preliminary set of consistent factors has been proposed to assist clinicians in identifying individuals at risk of poor recovery. Directions for the development of improved prognostic models are discussed. Current evidence is not strong enough to be able to confidently predict outcome after whiplash injury. There are some factors that have shown consistency across studies that may be useful as a preliminary guide only and not as directives for specific interventions. These include pain and/or disability levels, neck range of movement, cold and mechanical hyperalgesia and psychological factors of recovery beliefs/expectations, post-traumatic stress symptoms, depression, and pain catastrophizing. Further research is required to confirm and validate predictive factors identified in phase 1 studies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
