All models were adjusted for age, race, sex, BMI, NDI, smoking, baseline co-morbidities, medications
^aEstimated hazard ratios per increase of one standard deviation in the median long-term exposure to each traffic-related air pollutant
^bEvents include myocardial infarction, coronary revascularization, stroke, death from coronary heart disease, and death from cerebrovascular disease
^cEvents include myocardial infarction, coronary revascularization, and death from coronary heart disease
^dEvents include stroke and death from cerebrovascular disease
