The pirate plots (a combination of boxplots and violin plots) show the distribution of the ten most abundant species in the nasopharyngeal microbiome, according to the five metatranscriptome profiles. In the overlying violin plots, the width represents the probability that infants in a profile take on a specific relative abundance. The between-profile differences in the relative abundance were tested by Kruskal-Wallis test.
