  1. Comparisons between groups were tested by χ test and t-test. P < 0.05 was defined as statistically significant.
  2. aFrequency (%) and χ test; bMean and variance, and t-test. *P < 0.05.
  3. BMI body mass index, NC neck circumference, CVD cerebrovascular disease, ADA average duration of apnea, MDA maximum duration of apnea, ODI oxygen desaturation index, NMSBP nocturnal maximum systolic blood pressure, NMDBP nocturnal maximum diastolic blood pressure, AHI apnea hypopnea index, Mean SpO2 mean oxygen saturation, Minimum SpO2 minimum oxygen saturation.
  4. Numeric and categorical variables were reported as mean ± standard deviation and N (%), respectively.
