  • There is no statistically significant difference between the Country SA rate of 23.0% and the metropolitan Adelaide rate of 22.7%1.
  • No statistically significant underlying trend over the last decade in the proportion of people reporting living with arthritis was identified in the metropolitan Adelaide or Country SA time series1.
