All data were expressed as mean ± standard deviation. *P<0.05, **P<0.01, OSA group or HTN-OSA group versus NC group; †P<0.05, ††P<0.01, HTN-OSA group versus OSA group. BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; AHI, apnea and hypopnea index; LSaO2, lowest oxygen saturation; NC, normal control; OSA, obstructive sleep apnea; HTN, hypertension.
