  1. All participants were categorized into two groups by their OSAS severity (control, AHI ≤ 15; and OSAS, 15 < AHI). Concentrations of plasma VEGF, bFGF, and Hb the night before PSG and the next morning were measured (night and morning, respectively). Data are presented as mean values ± standard deviations. Statistical analysis for evaluation parameters among the categories was performed by the Student t-test.
  2. AHI apnea-hypopnea index, bFGF basic fibroblast growth factor, BMI body mass index, SpO 2  < 90% (% TST) percentage of total sleep time with oxygen saturation below 90%, Hb hemoglobin, ODI oxygen desaturation index, SpO 2 oxygen saturation with pulse oximetry, VEGF vascular endothelial growth factor.
