The effects of long-term continuous positive airway pressure on apnea-hypopnea index change following short-term that withdrawal in patients with obstructive sleep apnea.

The effect of long-term continuous positive airway pressure (CPAP) treatment on apnea-hypopnea index (AHI) after CPAP withdrawal remains unclear, especially in obstructive sleep apnea (OSA) patients screened from the population. To examine that, 1241 civil servants who participated in the annual physical examination were screened for OSA between September and December 2017.
