Figure 5.
Observed OTU (A), Shannon (B), and Simpson (C) diversity, and Bray-Curtis dissimilarity (D) illustrate clustering of P. aeruginosa and H. influenzae positive samples. Differences in the sputum microbial diversity of samples collected in relation to the growth of Pseudomonas aeruginosa (PA, n = 60) and Haemophilus influenzae (HI, n = 17) and in samples with neither (Neither, n = 56). The ellipses for each group represent the 90% confidence interval. The median and interquartile ranges (IQR) are represented by the middle, top, and bottom lines of each boxplot. Statistically significant comparisons were shown using the p-value.
