(A) α diversity (Shannon-Weiner [SW]) within groups was compared using the Kruskal-Wallis test with Dunn’s multiple comparisons test. Cystic fibrosis (CF) samples were significantly less diverse than immunocompromised (IC) and nonimmunocompromised (nIC) samples. (B) Influence of concurrent treatment antibiotics on diversity (Shannon-Weiner) within diagnosis groups by two-way ANOVA with Tukey’s multiple comparisons test. CF samples, with and without treatment antibiotics, were less diverse than IC samples. CF samples without treatment antibiotics were also less diverse than nIC samples without antibiotics. There was no significant reduction in diversity within diagnosis groups due to concurrent treatment antibiotic use. Abx = antibiotics.*0.05 > P > 0.01, **0.01 > P > 0.001, ****P < 0.0001.
