↵* Analysis: Negative binomial regression with repeated measures (generalised estimating equations); Dependent variable (continuous)=case count (dog-bite injury hospitalisations or rabies post-exposure prophylaxis) for calendar year per jurisdiction; Offset variable=log of population count; no. of observations=46.
↵† 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.
