Using a randomly selected cancer cases among non-Aboriginal people matched one to one with cases among Aboriginal by sex, year of birth, year of diagnosis and primary cancer site with observations right censored at a maximum of 24 months after diagnosis or at 31/12/2011
^#Average marginal effects represent the change in FLYLAD_{cancer 24-months}, the outcome variable, when moving from a predictor variable's reference category
