Figure. Annualized all-cause pneumonia hospitalization rates, by age group, race, and sex, per 1,000 children, Tennessee, USA, 1998–2013. A) <2 years of age; B) 2–4 years of age; C) 5–17 years of age. Asterisks indicate groups with a significantly higher rate than white girls within each period, determined on the basis of the 95% CI of the respective rate ratio (not shown). Error bars indicate 95% CIs of hospitalization rate. Periods were defined as follows: pre-PCV7, 1998–1999; early PCV7, 2001–2005; late PCV7, 2006–2009; and post-PCV13, 2011–2013.
