Abstract
PURPOSE: The primary objective of this cross-sectional study was to test factors associated with sleep apnea in patients with chronic kidney disease (CKD). The prevalence of sleep apnea was also assessed. METHODS: We recruited patients with CKD Stage 3-5 who lived in the St. John's area from September 2012 to December 2012. The Berlin Questionnaire and Short Form 36 Quality of Life Health Survey Questions (SF-36) were administered to all participants. RESULTS: We recruited 303 patients (41% female). A total of 157 (51.8%) patients had a high risk for sleep apnea. Higher body mass index and young age were correlated with sleep apnea. Physical component score of SF-36 (PCS) tested as a continuous variable indicated a significant association with the risk for sleep apnea (OR: 0.97, 95% CI: 0.94-0.99, p = 0.03). The association implies 3% change per one point increase in PCS. We categorized mental component score of SF-36 (MCS) into four quartiles, as the linearity assumption was violated. There was a 61% risk increase for poor sleep in those with an MCS score less than the 75th percentile, when compared to those above the 75th percentile (OR: 0.39, 95% CI: 0.21-0.71, p = 0.002). CONCLUSIONS: Sleep apnea is common in kidney patients. People who have low PCS and MCS scores are more prone to sleep apnea or vice versa. Our results also indicate that high BMI and young age are associated with sleep apnea.

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
