FIGURE 1—
Ratio of geometric means (GM) of air pollution by race/ethnicity stratified by study site: Multi-Ethnic Study of Atherosclerosis, 6 US communities, 2000–2002.
Note. Points represent the ratio of GM of fine particulate matter (PM2.5) and nitrogen oxides (NOX) concentrations comparing participants of each race/ethnicity to White participants. Horizontal lines represent 95% confidence intervals (CIs). Results were adjusted for age, gender, education, participant annual family income, census tract, median family income, and population size. Text provided for ratio of GM was rounded to 2 decimal places.
