Treatment with continuous positive airway pressure (CPAP) does not significantly alter the nasal microbiome. Longitudinal change of nasal microbiota comparing baseline samples with samples obtained after 3 months on treatment with CPAP showed no significant difference in (A) α diversity (Wilcoxon rank test P = ns), and (B) β diversity (permutational multivariate ANOVA P = ns). ns = not significant; PC = principal coordinate.
