Perioperative CPAP adherence and corresponding nocturnal oxygen saturation in CPAP adherent versus non-adherent OSA patients. a Perioperative CPAP adherence patterns. b Oxygen saturation parameters measured by overnight oximetry. Preop = pre-operative night; N = postoperative night; Adherent = CPAP adherent; Non-adherent = CPAP non-adherent, ODI = oxygen desaturation index, CT90 = cumulative time percentage with SpO2 < 90%, Data represented as mean with 95% CI, * p <  0.05 vs adherent
