Bold type indicates statistical significance.
*Adjusted by basic adjustment (baseline values of the variable analysed and age, gender, BMI and AHI).
AHI, apnoea–hypopnoea index; BMI, body mass index; EPAP, expiratory positive airway pressure; IPAP, inspiratory positive airway pressure; NIV, non-invasive ventilation.
