Data are presented as mean values ± SD or as number. OSA, obstructive sleep apnea, HTN, hypertension, BMI, body mass index, AHI, apnea-hypopnea index, TST90, total sleep time with oxyhemoglobin saturation below 90%, and SaO2, arterial oxygen saturation. Data are different from controls and OSA groups (). Data are different from controls and HTN groups ().
