The Effect of One Versus Two Nights of In-Laboratory Continuous Positive Airway Pressure Titration on Continuous Positive Airway Pressure Compliance
Bibliographic record
Abstract
OBJECTIVE: To investigate continuous positive airway pressure (CPAP) compliance after one versus two nights of CPAP titration. METHOD: A chart review and a telephone questionnaire interview were conducted in 110 sleep apnea patients who received one or two nights of CPAP titration. Of these patients, 78 followed through with phone interview. RESULTS: There was no difference in CPAP compliance between those who had one or two nights of CPAP titration. The titration pressures on the first and second nights were not significantly different. But there was significant improvement in sleep efficiency from the first to the second diagnostic night. CONCLUSION: One versus two nights of CPAP titration did not affect CPAP compliance, but sleep efficiency improved on the second diagnostic night and an extra titration study may be necessary for some patients, especially those with only one diagnostic night.

Full frame machine prediction
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.
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 source (direct Gemma or distilled Codex), not a consensus.
