Similarly, after including PM 2.5 in the models, odds ratios for cardiovascular disease remained significantly higher in the second ( p = 0.04), third ( p = 0.001), and fourth ( p = 0.001) and approached significance in the fifth ( p = 0.07) quintiles of vulnerability, and for cardiopulmonary disease, in the third ( p < 0.001), fourth ( p < 0.001), and fifth ( p < 0.001) quintiles of vulnerability, compared with census tracts with the lowest vulnerability scores.
