  1. Abbreviation: OR=odds ratio.
  2. aModels were adjusted for age, place of birth, education level, residential radon exposure, past history of lung diseases, any cancer in first-degree relatives, and intake of meat.
  3. bThe reference group consists of never exposed to the specific agent.
  4. cThe reference group consists of never exposed to any of the confirmed or suspected human carcinogens in the list. Bold values indicate P<0.05.
