hs-CRP: high-sensitivity C-reactive protein. OAHS: obstructive apnea-hypopnea syndrome. : number. AHT: arterial hypertension. ESS: Epworth sleepiness score. BMI: body mass index. AHI: apnea-hypopnea index. SpO₂: transcutaneous oxygen saturation. ODI: oxygen desaturation index. TST90: total sleep time with . FVC: forced vital capacity. FEV1: forced expiratory volume in 1 second. Italic values indicate statistically significant difference.
