^a Earliest self-reported fogger truck at residence among Long Island, New York women, Long Island Breast Cancer Study Project,1996-1997. “Total LIBCSP population” includes both fogger truck exposures ≤ 1972 and >1972, “Fogger truck <1972” and “Fogger truck >1972” definitions are mutually exclusive categories. “Ever” includes exposure >20, ≤20 and ≤14 years of age; “≤20 years of age” includes exposures ≤14 years of age.
^badjusted for 5-year age groups.
^cParticipants exposed (n<5) during susceptible windows not displayed for confidentiality purposes.
