AOR adjusted odds ratio, CI confidence interval, SHR sub-hazard ratio, ICD-O-3 International Classification of Diseases Oncology, SEIFA socio-economic index for areas (Index of relative socio-economic disadvantage).
aAll logistic regression models adjusted for age, sex, year of diagnosis, remoteness and SEIFA. ORs presented for Aboriginal peoples compared with non-Aboriginal people. Separate models for distant and distant/regional as an outcome.
bAll competing risk regression models adjusted for age, sex, year of diagnosis, remoteness, SEIFA and stage. SHRs presented for Aboriginal peoples compared with non-Aboriginal people. Death certificate only cases and cases found at post-mortem were excluded from survival analysis (1.5%) and, therefore, numbers included in stage and survival analyses differ slightly.
cColorectal cancers grouped together and separately for colon (ICD-O-3 C18) and rectum cancers (ICD-O-3 C19-C21).
dOnly females/ males included as relevant. Only female breast cancers included in the models.
eAll other cancer sites categorised to this group.
