Fig. 7: Nasopharyngeal lavage alpha diversity.

Measures of alpha diversity within NPL samples based on a evenness, b richness, c Faith phylogenetic diversity, and d Shannon diversity. e Omnibus tests for differences between any of the nine cohorts at each time point were performed with the Kruskal–Wallis tests in QIIME 2.0 (significant where P < 0.05). Values are represented as box and whisker plots where boxes denote interquartile range and upper and lower whiskers minimum and maximum, respectively. Each plot is organized by time point within the treatment. Asterisks denote significant pairwise comparisons (q < 0.20) between posttreatment time points and respective baseline values within individual cohorts. Sample sizes are reported in Table 2.
