Percent change in PON1 arylesterase (PON1A) and PON1 paraoxonase (PON1P) activity levels by tertile of compositea blood metal level, in the BioCycle Study (N = 250), Buffalo, NY (2005–2007).

aComposite tertiles definitions: high (in highest tertile of at least two metals), low (in lowest tertile of at least two metals), medium (else).bThere were only 115 women with diet information available for the adjusted models.cT3: Highest, T2: Middle, T1: Lowest.A: unadjusted.B: adjusted for age (continuous), race (white, black, Asian, other), BMI (continuous), smoking (current, no), leafy green servings (continuous), fish servings (continuous), shellfish servings (continuous), concurrent metal levels (tertiles).
