Stratum-specific effects of 1-yr average non-freeway NRAP by A) the ratio of Teff to Treg cells counts in serum, B) the ratio of M1 to M2 cells counts in serum, C) M1 cell counts in adipose tissue. The ratio of Teff to Treg in serum, M1 to M2 in serum, and M1 in adipose tissue were dichotomized at the median of 1.10, 0.14, and 4687 cells/g, respectively (Supplementary Table 2). The lighter color indicates the confidence intervals. The reported effect estimates were scaled to an interquartile (1.1 ppb) increase in non-freeway NOx. All the models were adjusted for age, sex, race, ethnicity, and BMI
