1 World Health Organization definition of regions

2 All asthma prevalence estimates were calculated using post satisfaction weights unless otherwise indicated

3 Post stratification weights were not available from these countries, so sampling weights were used in calculating the prevalence estimates

4 Weights were not provided these countries

5 Standard errors were missing due to a sampling unit
