  1. All models were adjusted for age, race, sex, BMI, NDI, smoking, baseline co-morbidities, medications
  2. aEstimated hazard ratios per increase of one standard deviation in the median long-term exposure to each traffic-related air pollutant
  3. bEvents include myocardial infarction, coronary revascularization, stroke, death from coronary heart disease, and death from cerebrovascular disease
  4. cEvents include myocardial infarction, coronary revascularization, and death from coronary heart disease
  5. dEvents include stroke and death from cerebrovascular disease
  6. §P-value < 0.05 for interaction term, indicating statistically significant differences by elderly status in the association of the air pollutant with risk of the cardiovascular event
