  1. aThree population groups (total, Indigenous on-reserve and Indigenous off-reserve) divided by 16 HSDAs and 2 time periods (1998–2003 and 2004–2008)
  2. bThe dependent (Y) variable is SRR of hospitalization due to intentional injury, and regression is weighted by person-years
  3. cUnweighted mean and standard deviation (SD) of the independent (X) variable
  4. dB = regression coefficient
  5. eSE = standard error of the regression coefficient
  6. fp = probability that B = 0
  7. gSRR change per SD = BxSD. One SD change in the independent variable is associated with absolute change in the Standardized Relative Risk of injury by this amount
  8. hLower limit of the 95% confidence interval for the SRR change per SD
  9. iUpper limit of the 95% confidence interval for the SRR change per SD
