  1. * Population-weighted mean of the x-variable, 2001 and 2006 Census, for the specified population group
  2. Difference between mean of the specified population group and mean of the total population
  3. Predicted absolute change in standardized relative risk of injury (calculated as B x difference), where B is the regression coefficient in the best-fitting multivariable model
