Abstract
PURPOSE: Sodium oxybate (SXB) is approved for cataplexy and excessive daytime sleepiness in narcolepsy. Obstructive sleep apnea syndrome (OSAS) affects ∼9-50% of narcoleptics. Effects of 2-week SXB administration on apnea-hypopnea index (AHI), oxygen saturation (SaO(2)), and sleep architecture were investigated in OSAS patients. METHODS: OSAS patients (n = 48) received 2-week SXB or placebo (PBO) treatment with polysomnography at baseline and day 14. The primary outcome measure was change from baseline in mean AHI. Secondary outcomes included changes from baseline in SaO(2), and sleep architecture. RESULTS: Compared with PBO, SXB significantly increased reduction in mean AHI and obstructive apnea index with SXB (-0.8 ± 13.3 vs. -8.2 ± 10.0; p = 0.0327 and 3.54 ± 11.1 vs. -4.72 ± 7.7; p = 0.0054, respectively) and significantly increased change in slow wave sleep duration (5.2 ± 25.0 min vs. 29.4 ± 37.0 min; p = 0.0038). There were no differences between treatments in SaO2, central apneic events, or other measures. Adverse events, most commonly headache, were noted in nine of 27 (33%) and six of 23 (26%) patients receiving SXB and PBO, respectively. CONCLUSIONS: Short-term use of 4.5 g/night SXB did not generate respiratory depressant effects in OSAS patients as measured by AHI, obstructive apnea events, central apneas, and SaO2. Extended use of SXB in higher therapeutic doses in OSAS has not been studied, and merits caution.

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
