a ORs calculated with strata for the variables age and province of residence.
b ORs adjusted for statistically significant medical variables (history of measles, mumps, cancer, allergy desensitization shots, and a positive family history of cancer in a first-degree relative) and with strata for the variables age and province of residence.
c Malathion is an organophosphorus insecticide which has been used indoors as a fumigant.
