aModel 1 adjusted for age and province.
bModel 2 adjusted for: age, province, ethnicity, pack-years, alcohol, BMI, years of education, moderate physical activity, strenuous physical activity, total caloric intake, exposure to pesticides, and exposure to cadmium.
cModel 3 adjusted for: model 2 variables, neighborhood SES index, and neighborhood greenness.
dIQR 1.45 ppb for satellite NO2, 15.18 for fused NO2, and 15.39 for national LUR NO2.
eIQR 3.56 ppb for satellite PM2.5 and 4.48 for fused PM2.5.
