O042 Does severity reflect burden? Equivalence of REM- and non-REM-predominant OSA Open
Introduction REM-predominant Obstructive Sleep Apnoea (REM-OSA) is often considered a distinct clinical phenotype, yet evidence for meaningful differences in symptoms, comorbidities, or prognosis remains inconsistent. Equivalence testing m…
