Figure 2.

Predicted means of waist-to-height ratio trajectories by tertiles of urinary PAH metabolites across 7–16 years old computed from mixed-effects models in 404 girls, BCERP Northern California site: 2-naphthol, Σfluorene, Σphenanthrene, 1-hydroxypyrene, ΣmolPAHs. Low (dotted line) is the growth trajectory among girls in the lowest tertile of the baseline urinary PAH metabolite concentrations, medium (dash-dot line) is the middle tertile, and high (solid line) is the growth trajectory among girls in the highest tertile of the baseline urinary PAH metabolite concentrations.
