Serotype-specific differences in mortality between serotypes.

<p>The line shows the absolute case fatality rate for serotype 14, which was used as reference in the logistic regression. The p-values of this regression are shown above each bar. The whiskers show the 95% confidence intervals based on a binomial distribution. When there are no serotypes with ≥50 cases an empty plot is shown. a) Under 5 years; b) 5–64 years; c) 65+ years.
