PATIENT CHARACTERISTICS ASSOCIATED WITH SURGEONS’ RATINGS OF PHYSICAL DEFORMITY IN ADOLESCENT IDIOPATHIC SCOLIOSIS (AIS).
Bibliographic record
Abstract
Five surgeons independently rated clinical photographs of forty patients with AIS. Ratings of shoulder blades, shoulder symmetry, and waist symmetry were related to “overall appearance”, and were also correlated with rib prominence and Cobb angle. Because the components of surgeons’ ratings of appearance differed, this may lead to inconsistent recommendations regarding surgery. To identify patient characteristics associated with surgeons’ ratings of patient physical deformity in Adolescent Idiopathic Scoliosis (AIS). Five surgeons independently rated clinical photographs of forty patients with AIS. Surgeons separately rated the appearance of patients’ shoulder blades, shoulder symmetry, waist symmetry and also rated their “overall appearance ” [in five categories from zero (best) to five (worst)]. The following clinical and radiographic data was also collected: rib prominence, vertebral rotation, shoulder height, spinal imbalance, Cobb angle, age, sex, and body mass index. Surgeons’ mean rating for “overall appearance” was moderately correlated with rib prominence (r = 0.48), vertebral rotation (r = 0.44) and Cobb angle (r = 0.53). Surgeons’ rating of patients’ “overall appearance” was affected by each of: shoulder blades (p = 0.001), shoulder symmetry (p = 0.01) and waist symmetry (p = 0.001). However, each surgeon weighted components of patients’ appearance differently to arrive at their overall rating of appearance (p Because patients’ physical appearance is an important element of surgical decision making, differences among surgeons could be contributing to inconsistent recommendations. Surgeons’ ratings of physical appearance are based on surgeons’ ratings of patients’ shoulder blades, waist symmetry and shoulder symmetry but surgeons weight those elements differently. Surgeon decision making is complicated. It is based on radiographs and subjective assessment. Patients’ appearance undoubtedly influences surgeon recommendation for surgery. We need to clarify surgeons’ ratings and improve the criteria for surgeon decision making.

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.
