The Utility of the McGill Overnight Oximetry Score for the Moderate to Severe Obstructive Sleep Apnea Syndrome in Korean Children
Bibliographic record
Abstract
We conducted this study to evaluate the utility of the McGill oximetry score (MOS) to rule out moderate to severe obstructive sleep apnea syndrome (OSAS) in Korean children. Methods: We performed a cross-sectional study by using medical and polysomnography (PSG) records from our sleep disorder center. We assessed 58 PSG records conducted from September 2011 to December 2015. MOS was calculated from the overnight oximetry tests performed as part of PSG. We also investigated age, gender, height zscore, weight z-score, body mass index z-score, obesity, underweight, and pediatric daytime sleepiness scale. Results: MOS revealed inconclusive (score 1) in 50 (68.2%), and abnormal (2-4) in 8 (13.8%) of PSG results. And moderate to severe OSAS were diagnosed in 20 (34.5%) records according to the apnea-hyponea index (5). In a multivariate logistic regression analysis, age [adjust odds ratio (OR) 0.8; p-value=0.013] and abnormal MOS (adjust OR 39.5; p-value=0.007) showed statistical significance between normal/mild OSAS group and moderate/severe OSAS group. MOS had a positive predictive value of 88%, a negative predictive value of 74%, a sensitivity of 35% and a specificity of 97% for detecting moderate/severe OSAS. Con- clusions: In our small group study, MOS cannot exclude moderate to severe OSAS. Further prospective studies are needed.

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.
