  1. Multivariable model statistics: R2 = 0.912, F = 177.632, p <0.001
  2. aThree population groups (total, Indigenous on-reserve and Indigenous off-reserve) divided by 16 HSDAs and 2 time periods (1998–2003 and 2004–2008)
  3. bThe dependent (Y) variable is SRR of hospitalization due to intentional injury, and regression is weighted by person-years
  4. cUnweighted mean and standard deviation (SD) of the independent (X) variable
  5. dB = regression coefficient
  6. eSE = standard error of the regression coefficient
  7. fp = probability that B = 0
  8. 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
  9. h95% confidence limits of the SRR change per SD
