Figure 3: Assessment of effect modification by maternal asthma.

Figure 3:

Adjusted relative risks (RR) and 95% confidence intervals for the association between each outcome and a two-fold increase in individual OH-PAH metabolite are displayed. Strata specific results were derived from interaction models. Displayed p-values are for the interaction term. Associations are adjusted for child age at assessment, child sex, study site, batch of OH-PAH analysis, urinary specific gravity, maternal age, education, race, pre-pregnancy, household income, parity, maternal history of asthma, enrollment year, postnatal smoke exposure, and season of birth.

Abbreviations: OH-PAH – mono-hydroxylated-polycyclic aromatic hydrocarbon; 1-PYR - 1-hydroxypyrene; 2/3/9 -FLUO – combined 2- and 3- and 9-hydroxyfluorene; 1/9-PHEN – combined 1- and 9-hydroxyphenanthrene; 3-PHEN - 3-hydroxyphenanthrene; 2-PHEN - 2-hydroxyphenanthrene; 2-NAP - 2-hydroxynaphthalene; 1-NAP - 1-hydroxynaphthalene.
