Relative risk of death in relation to the deprivation and pollution indices and the traffic exposure indicator. All proportional hazards models were adjusted for age, sex, lung function, BMI, and diagnoses of chronic ischaemic heart disease, obstructive lung disease, and diabetes. In the univariate models, the exposure variables were included separately
