1 Lipid adjusted and log-transformed polychlorinated biphenyls (ng/g); 2 Geometric means calculated after applying NHANES sampling weights.; a PCB levels significantly higher in non-Hispanic White with risk factors for PAH vs. non-Hispanic White controls (p < 0.05); b PCB levels significantly higher in race category “other” with combined risk factors for PAH compared to control “other” (p < 0.05).
