Comparison of pollutant-dependent CHD mortality and hospitalization risks between EJ and non-EJ census tracts in Allegheny County. The component of disease risk attributed to BC or NO2 was calculated for each census tract as described in Fig. 5. Data shows the distribution of all individual risk values compared between non-EJ (n = 265) and EJ (n = 136) tracts. Dotted lines represent the median and solid lines represent the interquartile range. Asterisks denote statistically significant difference between EJ and non-EJ tracts by Mann-Whitney U-test (p < 0.001)
