  • a ORs are adjusted for age, cancer registry, race/ethnicity, and education. All ORs are in reference to controls.

  • b Cases of immunoblastic NHL (n = 108) and five cases of lymphoblastic NHL (n = 5). All cases with insect bite allergies were immunoblastic NHL.

  • c Plant allergies include those to pollen, hay, grass, leaves, and molds.
