*Adjusted with age, parity, gestational age at BP assessment.
**Adjusted with age, parity, gestational age at BP assessment and BMI at enrolment.
BMI, body mass index; AHI, apnea-hypopnea index; REM-AHI, apnea-hypopnea index during REM sleep; NREM-AHI, apnea-hypopnea index during NREM sleep; 4% ODI, 4% oxygen desaturation index; SpO2, oxygen saturation during sleep; TST < 90%, total sleep time with oxygen saturation < 90%.
Bold values means p-value < 0.05.
