Incidence rate ratios for victimisation-related injury admission: multivariable analyses where interaction with country was significant
| Age group | Factor | England | 95%CI | Western Australia | 95%CI | p-value for interaction w/country** |
|---|---|---|---|---|---|---|
| 11 – 15* |
Female |
0.83 |
(0.74, 0.95) |

<0.001 |
| 16 – 17* | Deprivation |

| Female | 0.37 | (0.32, 0.44) | 0.83 | (0.71, 0.98) | <0.001 |
* Adjusted by year of age and deprivation.
** log (μ) = a + b. WA + c. Deprivation + d. WA. Deprivation + e. Age + f. WA. Age + g. Gender + h. WA. Gender.
Where a, c, e and g are the intercept and coefficients for England, and b, d, f and h are the intercept and coefficients for Western Australia. Deprivation used as numeric (Incidence rate ratio represents increased risk per quintile of deprivation, from least to most deprived).
