Adjusted logistic regression for the association between radon potential and inclusion of radon activity in NCCCP awardee state cancer plans

	Odds ratio (95% confidence interval)
Percent EPA zone 1	1.04 (1.02, 1.07)
Population-weighted EPA zone 1	0.16 (0.05, 0.51)

Regression analyses included all states and the District of Columbia with high-quality cancer incidence data (N = 50, Nevada was excluded). Rates were adjusted for lung cancer incidence and adult smoking prevalence. Cancer incidence data were from the most recent year of United States Cancer Statistics and covered 99% of the U.S. population. Smoking data were from the 2016 Behavioral Risk Factor Surveillance System. EPA radon zones and population-weighted radon zones were calculated as described in the “Methods”. Population weights were from the U.S. Census Bureau
