Descriptive statistics for our variables of interest, proportion of Aboriginals per health region and distance to nearest radiotherapy centre, were calculated and are shown in Table 1. In univariate analyses, distance to radiotherapy and each sociodemographic variable were significantly associated with MIR (p < .05), except for physical activity (% moderately active or active). However, as previously mentioned, due to a high VIF for the proportion of Aboriginals variable (12.0), this variable was removed, and the regression analysis could not be completed as this was one of our variables of interest (data not shown).
