Adjusted for: Aboriginal status, homeless, police harassment without arrest;

Migrant status, homeless, police harassment without arrest

ns = not significant in bivariate analysis and thus not explored in multivariable analysis; or not significant in multivariable analysis in Table 5a, without adjusting for police harassment and thus not explored in multivariable analysis adjusting for police harassment

nc = police harassment not identified as a key confounder and thus not explored in multivariable analysis
