a ORs calculated with strata for the variables of 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 of age and province of residence.
c Amide fungicides include captan and a mixture of carbathiin, thiram, and lindane (Vitavax).
d Aldehyde fungicides include formaldehyde and a mixture of formaldehyde and iprodione (Rovral Flo).
e Mercury-containing fungicides include mercury dusts (Ceresan, Reytosan, and Agrox) and mercury liquids (Panogen, Leytosol, and PMAS).
