Epworth sleepiness scale, basal arterial blood gas results, sleep study findings and therapeutic intervention for the 2 cohorts.

Values are expressed as mean ± SD or No. of patients (%). PaO2: arterial oxygen pressure; PaCO2: arterial carbon dioxide pressure; AHI: apnea-hypopnea index; DI4: nocturnal desaturation ≥ 4% index; CT90%: cumulative percentages of sleep time with SaO2 Epworth sleepiness scale, basal arterial blood gas results, sleep study findings and therapeutic intervention for the 2 cohorts.

数据以均值±标准差（mean ± SD）或患者例数（百分比）形式表示。其中：PaO2为动脉血氧分压（arterial oxygen pressure）；PaCO2为动脉血二氧化碳分压（arterial carbon dioxide pressure）；AHI为呼吸暂停低通气指数（apnea-hypopnea index）；DI4为夜间血氧饱和度下降≥4%指数（nocturnal desaturation ≥ 4% index）；CT90%为睡眠期间血氧饱和度（SaO2）的累计时间百分比。上述爱泼沃斯嗜睡量表（Epworth sleepiness scale）、基础动脉血气检测结果、睡眠监测结果及治疗干预措施，均来源于这两个队列。
