  • * Analysis: negative binomial regression with repeated measures (generalised estimating equations); Dependent variable (continuous)=case count (dog-bite injury hospitalisations) for calendar year per jurisdiction; Offset variable=log of population count; no. of observations=414.

  • Denotes magnitude of difference in rate of dog-bite injury hospitalisations associated with each unit increase in explanatory variable when all other variables are held constant.

  • Reference category.

  • BSL, breed-specific legislation.
