BDE-47 and BDE-100 adjusted for race/ethnicity; BDE-153 adjusted for age.

Annual percent increase (API) converted from time trend coefficients (β) obtained from regressing log₁₀ PBDE concentration ((ng/g lipid) on date of sample collection, expressed as year and fraction of a year, where API = 100*(10^β − 1).

CI = Confidence interval.
