Table 3 Incidence rate ratios for victimisation-related injury admission: multivariable analyses where interaction with country was significant

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

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
Female 0.37 (0.32, 0.44) 0.83 (0.71, 0.98) <0.001
  1. * Adjusted by year of age and deprivation.
  2. ** log (μ) = a + b. WA + c. Deprivation + d. WA. Deprivation + e. Age + f. WA. Age + g. Gender + h. WA. Gender.
  3. 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).
