Most parsimonious model: conditional logistic regression analyses that contained individual chemical pesticides and important covariates (P < 0.05)

Among individual pesticides, carbaryl, lindane, DDT, and malathion insecticides, and captan fungicide user/nonuser were included in the initial multivariate model and found not to contribute significantly to the risk of NHL.
