Table 2.
Respiratory parameters derived from portable monitoring and sleep questionnaires for the entire population and for patients with and without obstructive sleep apnea.
| Total population (n = 90) | No OSA (n = 53) | OSA (n = 37) | p-value | |
| RDI, e/h | 10.2 (4.5–24.8) | 5 (2.7–8.1) | 30.3 (21.2–39.3)*) | <0.001 |
| Lowest SpO2, % | 84 (78–88) | 87 (83–89.5) | 80 (75.7–82.5)*) | <0.001 |
| Berlin high risk, n (%) | 36 (40) | 13 (25) | 23 (66)*) | <0.001 |
| Snoring, n (%) | 47 (52) | 13 (35) | 24 (65) | 0.056 |
| Tiredness, n (%) | 35 (39) | 18 (34) | 19 (51) | 0.152 |
| BMI ≥30 kg/m2, n (%) | 22 (24) | 9 (16) | 13 (35) | 0.080 |
| Epworth | 7 (3–11) | 7.5 (3.5–11) | 7 (3–12.2) | 0.924 |
Values are presented as percentages, means±SD or medians (interquartile ranges) for the variables with skewed distribution. OSA: obstructive sleep apnea. RDI: respiratory-disordered index; BMI: body mass index.
