Study specific and pooled risk ratios (RRs) for death from bacteremic pneumonia compared to serotype 14. Closed diamonds represent study-specific RR+/−95% CI. Open diamonds represent the pooled RR+/−95% CI. I2 denotes the amount of variation in the RR due to heterogeneity. Only studies with ≥ 10 isolates of the serotype are shown though all studies were used to calculate the RR and evaluate heterogeneity.
