Finding F-1628

“However, no statistically significant association was observed between indoor radon exposure and lung cancer risk, neither in the crude analysis (OR = 1.000, 95% CI = 0.995–1.004, p = 0.983) nor in the adjusted analysis (OR = 0.995, 95% CI = 0.988–1.003, p = 0.250).”

Structure

Factor: Radon
Outcome: Lung cancer
Study design: case-control study in a community near gold mine tailings: indoor radon measured in the participants' dwellings and related to lung cancer, with smoking and dwelling location as further factors (class 4)
Effect: OR 1.000 (0.995–1.004)
Caveat: a null result: the interval is narrow and sits on 1, so the study finds no association in this community
