Abstract
Background: Cobb angle measurement is a standard method for quantification of scoliosis in patients with adolescent idiopathic scoliosis (AIS).Clinicians rely on Cobb angle measurements to guide treatment decisions.Timely and accurate diagnosis at the primary care level is required to screen patients eligible for timesensitive brace treatment, which is typically delivered in the tertiary care setting.Therefore, accurate and reliable measurement of Cobb angle at the community level is crucial.This study investigated the agreement in Cobb angle measurement between radiologist and the treating spine surgeon.Methods: A retrospective audit of radiographs for patients with AIS was performed.A random sample of 80 patients was selected and radiographic reports (Cobb angle, Risser stage and end vertebrae) by radiologists and spine surgeons were compared.To assess interrater reliability, interclass correlation coefficients (ICC) with 95% confidence intervals (CIs) were computed.Interclass correlation coefficients < 0.70, 0.70-0.79,0.80-89, and 0.9-0.99 were considered poor, fair, good and excellent reliability, respectively.All radiographs were assessed for quality.Results: The agreement of Cobb angle between spine surgeons was excellent (ICC 0.96, 95% CI 0.94 to 0.97).The agreement between spine surgeons and radiologists was poor (ICC 0.65, 95% CI 0.13 to 0.97).The ICC between spine surgeons and community radiologists and pediatric radiologists was poor (ICC 0.45, 95% CI 0.17 to 0.66) and good (ICC 0.87, 95% CI -0.46 to 0.96), respectively.However, 35 out of 80 radiographs performed did not meet the standard criteria.Risser stage was not reported in 56 of the 80 radiology reports.Interclass correlation coefficients between spine surgeons and radiologists for Risser stage was poor (ICC 0.625, 95% CI 0.325 to 0.794).For end vertebrae identification, there was absolute agreement of end vertebrae identification in 23 of the 80 scans.Conclusion: This study demonstrated a significant disagreement in Cobb angle measurement between radiologists and spine surgeons, which may negatively affect referral wait times and timely treatment for AIS.Quality improvement initiatives, such as continuing medical education, to improve Cobb angle measurement among community radiologists is required to improve scoliosis screening at the primary care level.

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.
