Abstract
STUDY OBJECTIVE: To determine whether mucosal sensory dysfunction is present at multiple upper-airway sites in patients with obstructive sleep apnea (OSA). DESIGN: Physiologic testing of consecutive patients with OSA and nonsnoring controls. SETTING: University hospital sleep center. PARTICIPANTS: Thirty-nine subjects with OSA and 17 controls. INTERVENTIONS: Endoscopic testing was used to determine sensory detection thresholds for air-pressure pulses delivered to the oropharynx, velopharynx, hypopharynx, and larynx (aryepiglottic eminence). The air-pulse stimulus intensity required to elicit the protective laryngeal adductor reflex was also determined. MEASUREMENTS AND RESULTS: There was a significant impairment in sensory detection threshold for OSA versus control subjects in the oropharynx, as previously described by ourselves using other techniques, as well as at the velopharynx (median 11 mm Hg [confidence interval 9-11] for subjects with OSA vs 8 mm Hg [confidence interval 4-11] for controls, P = .03) and, at the larynx, 4 mm Hg [confidence interval 2-9] for subjects with OSA vs 2 mm Hg [confidence interval 2-3] for controls, P < .001). The threshold stimulus intensity for the laryngeal adductor reflex was also significantly higher for OSA subjects. For OSA patients with abnormal laryngeal sensation (61% of OSA subjects), there were significant correlations between laryngeal sensory values and measures of apnea severity, including apnea-hypopnea index (r = 0.82, P < .001) and nadir SaO2 (r = -0.48, P < .05). CONCLUSION: Mucosal sensory function is impaired at multiple upper-airway sites in OSA.

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 it
