Fig. 9: Nasopharyngeal lavage taxa frequency at the genus level.

Heatmap denotes the mean log10 frequency of genus-level taxa observed in NPL samples at each time point, within the treatment. Darker boxes denote lower prevalence, and lighter boxes denote greater prevalence. Significant taxa per ANCOM at 2DPT (*), 5DPT (■), and 7DPT (†) are depicted by specified symbols. No significant differences were observed for baseline or 9DPT genera. Sample sizes are reported in Table 2.
