  • Data are presented as mean±sd, unless otherwise stated. BMI: body mass index; SBP: systolic blood pressure; DBP: diastolic blood pressure; BRS: baroreceptor sensitivity; AHI: apnoea–hypopnoea index; ODI: oxygen desaturation index; SpO2: oxygen saturation measured by pulse oximetry; AAI: autonomic arousal index; ns: nonsignificant. Significance was determined by t-test or Chi-squared difference between women and men.
