Cross-country comparison of victimisation-related injury admission in children and adolescents in England and Western Australia

Table 3 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)	1.5	(1.25, 1.79)	<0.001
16 – 17*	Deprivation	1.32	(1.25, 1.39)	1.21	(1.15, 1.28)	0.04
16 – 17*	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).
