Average values per trimester or entire pregnancy
Units of measure: all particulates, PAH was measured in nanogram/meter cubed and the rest (all gases) were measured in part per billion by volume. Point estimates reflect odds of having Wilms tumor per inter-quartile increase in the mean concentration of the respective air toxic.
Adjusted for birthyear
Adjusted for the following variables: birth year, maternal age, maternal race/ethnicity, parity, census-based socioeconomic status
Includes sum of average concentrations of six hydrocarbons: benzo[a]pyrene, , benzo[b]flouranthene, benzo[ghi]perylene, benzo[k]flouranthene, dibenz[a, h]anthracene, and indeno[l, 2, 3-c,d]pyrene
