50th, 90th, and 95th percentiles by age and site for mean RR

RR=respiratory rate. Estimated percentiles obtained from a generalised additive regression model for location, shape, and scale fitted to RR data. The observed data points for all settings are plotted in grey. Smooth lines represent site-specific estimated percentiles by age. The blue step line indicates the thresholds recommended by WHO for determining abnormal RR. The table at the top of each panel summarises the mean difference in RR between pairs of countries.
