^aPercentage changes in rate. Rate was calculated by dividing ArADE admissions in the corresponding subgroup by the corresponding column total of ArADE admissions of the respective year. Percentage change was calculated using 2001 rate as the base
^bRate change in number of ArADE admissions from 2001 to 2011 using 2001 as the base
*p ≤ 0.01, which indicates there is a significant difference between areas of bottom-half income and top-half income with regard to change in ArADE admissions
^† p ≤ 0.01, which indicates change in rates over time were significantly different between areas of bottom-half income and top-half income in the specific age group
