Figure 1.

Figure 1A plots cluster of pollutants, namely, WB 7, S O 2, P A H 2, P A H 7, P A H 25, and N O 2, and 1B plots cluster of pollutants, namely, retene, WB 2, P A H 5 plus, P A H 2, and P A H 29 plus, on the y-axis, across odds ratios (95 percent confidence intervals) 0.1, 0.2, 0.5, 1, 2, 5, and 10 on the x-axis.

Odds ratios (ORs) per 1 standard deviation increase in exposure for different exposure clusters in the full population (A) and the smoky coal subpopulation (B). Exposure clusters were polycyclic aromatic hydrocarbon (PAH) 25 [consisting of 25 PAHs, including benzo(a)pyrene (BaP) and 5-methylchrysene (5-MC)], WB7 [consisting of seven wood burning–associated exposures, including fine particulate matter with aerodynamic diameter ≤2.5μm (PM2.5)], PAH7, PAH2, and two clusters consisting of the single exposures, nitrogen dioxide (NO2) and sulfur dioxide (SO2), respectively (See also Table S2 for complete listing of compounds in each cluster). Note: CI, confidence interval.
