  1. aReflects probability of use of insecticide active ingredient for year 2000, based on NCI Pesticide Exposure Matrix [21].
  2. bObserved reflects statistical significance of association from multivariable regression models presented in Table 3.
  3. c +, positive association, 95% confidence interval (CI) does not include 1.
  4. dEmpty cell reflects no association, 95% CI includes 1.
