Figure 1.

Forest plot showing hazard ratio estimates of association between living/working on a farm or household insecticide exposure and lympho-hematapoetic neoplasms. All exposures were categorized dichotomously. The referent categories for all exposures were defined as the group of women not exposed to that particular metric. Exposures were entered into the models individually. The baseline hazard functions were stratified by age at baseline and a time varying indicator for extension study participation. All models were adjusted for age, race/ethnicity, education, United States region of residence, occupational type, body mass index and smoking status.
