Serotype against observed absolute densities of pneumococcal serotypes.

<p>Serotype against observed absolute density for samples where a single serotype or strain was identified in the microarray (A) and for all samples (B). The red dots denote individual measurements of density. In the box and whisker plots, for each serotype, the central line denotes the median of the distribution, the box edges denote upper and lower quartiles and the whiskers extend 1.5 times the interquartile range past the quartiles. The black dots denote outliers (also shown in red), and the dotted vertical line marks the overall median as a guide to the eye. Numbers of measurements for each serotype are shown to the right of the y axis. Boxplots are ordered by median value, from lowest (bottom) to highest (top) of the solo serotypes in both panels.</p

Distribution of carriage density for serotype.

<p>Kernel Density plot showing the distribution of density plotted for different numbers of distinct serotypes recovered per child. The density of carriage does not differ with the number of serotypes found.</p

Serotype density against relative abundance.

<p>Serotype density against observed relative abundance. For each serotype, the median density is plotted against the relative abundance as a percentage of the entire sample, and horizontal lines denote interquartile ranges. Coloured symbols denote individual serotypes.</p
