Table 1 Baseline characteristics of subjects included in the trial.
| Item | Total |
|---|---|
| Subject number | 68 |
| Male sex | 68 |
| Age | 64.9±12.4 |
| Body mass index (kg/m) | 25.0±4.0 |
| Systolic blood pressure (mmHg)* | 145.2±20.2 |
| Diastolic blood pressure (mmHg) | 70.1±25.4 |
| Total sleep time (h) | 6.8±2.2 |
| Oxygen desaturation index of 5% (/F) | 20.6±15.4 |
| Risk Index (/F)** | 24.7±15.6 |
| * 1 mmHg=0.133 kPa; ** Risk Index=Sum of AHI assessment points and FL/FS assessment points. AHI is calculated as follows: AHI×1F=number of points (eg, AHI=5/F×1F=5 points), where F represents the number of FL/FS points assessed during the evaluation period. The formula for FL/FS points is: Risk Index=10×(0.8×FL+1.2×FS)/f, where FL=number of breaths with no snoring restriction, FS=number of breaths with snoring restriction, and f=total number of breaths. AHI – apnea/hypopnea index. | |
