a HRs are given for each pollutant in two-pollutant models. HRs scaled to IQRs are provided in Appendix Table D.4; available on the HEI website.

b Fully adjusted models are stratified by sex, age (5-year categories), and recent immigrant status and are adjusted for income adequacy quintile, visible minority status, Indigenous identity, educational attainment, labor-force status, marital status, occupation, and ecological covariates of community size, airshed, urban form, and four dimensions of Can-Marg (instability, deprivation, dependency, and ethnic concentration).

b Deaths were rounded to the nearest 100 for confidentiality.

c HRs are presented as per 10-μg/m3 increase.
