Bold type indicates statistical significance.
p Values of intra-group differences (2 months − baseline): *p<0.05; †p<0.01; ‡p<0.001.
p Values of inter-group differences unadjusted or adjusted by basic adjustment (baseline values of the variable analysed and age, gender, BMI and AHI).
AHI, apnoea–hypopnoea index; BMI, body mass index; ESS, Epworth sleepiness scale; FOSQ, Functional Outcomes of Sleep Questionnaire; NIV, non-invasive ventilation; SF 36, Medical Outcome Survey Short Form 36; VAWS, visual analogue well-being scale.
