Australia, 1999–2006 Figure 3.11: Distribution of severity of asthma among adults attending general practitioners, 1999 to 2006 Notes: In data point for 2003, moderate section also includes those whose asthma was classified as severe. In data point for 2000 the mild category also includes adults whose asthma was classified as being very mild. In data point for 1999, asthma severity classifications were not available for 4.2% of adults and, therefore, the data point does not add up to 100%. Source: AIHW: Britt & Miller 2007.
