  1. 1 World Health Organization definition of regions
  2. 2 All asthma prevalence estimates were calculated using post satisfaction weights unless otherwise indicated
  3. 3 Post stratification weights were not available from these countries, so sampling weights were used in calculating the prevalence estimates
  4. 4 Weights were not provided these countries
  5. 5 Standard errors were missing due to a sampling unit
