  1. aRelative Risk (RR) risk of total Indigenous drowning relative to total Non-Indigenous drowning by age group
  2. *p < 0.05; **p < 0.01; ***p < 0.001 used to denote significance for change over the seven year period
  3. bRR (and 95 % CI) has not been calculated because one of the incidence rates is equal to 0
