Note: CI = confidence interval, IRR = incidence rate ratio.
↵* Rates are calculated as cases per million age-related population using data from the Canadian census in 1996, 2001 and 2006.
↵† IRR = 1.00 indicates equal incidence in both groups; IRR >1 indicates higher incidence among Aboriginal children and young adults than among white children and young adults.
