Data area shown as mean ± standard deviation [range]. The OSA severity classes are none with AHI < 5, mild with 5 AHI < 15, moderate with 15 AHI < 30, and severe with AHI 30. Sleep efficiency is ratio of total sleep time to time in bed. AI and HI are respectively the number of obstructive apneas and hypopneas per hour of sleep. PLMI is periodic leg movement index calculated as number of periodic leg movements events per hour of sleep. The last row reports the five most common sleep disorder categories in the datasets (according to the primary diagnosis).
