Data are presented as mean±sem. Merged group data (continuous positive airway pressure (CPAP) plus autoadjusting CPAP). DIAG: diagnostic polysomnography; THER_INI: therapy initiation; 3M: follow-up at 3 months; 9M: follow-up at 9 months; AHI: apnoea/hypopnoea index; ODI: oxygen desaturation index; ArI: arousal index; ESS: Epworth Sleepiness Scale. *: p<0.05 between groups at the same time-point; **: p<0.01 compared with DIAG, same group.
