Table 3a-3c:

Excess relative rates of lung cancer incidence per 100 working level months (ERR/100 WLM^{^} among male uranium miners in the Příbram region of the Czech Republic, 1977–1996. Modeled as continuous WLM (3a), exposure rate (3b), and windows of time since exposure (3c).

3a. Continuous WLM
	Never Smokers		Smokers		Overall
	ERR/100 WLM	95%CI	ERR/100 WLM	95%CI	ERR/100 WLM	95%CI
	0.12	−0.05, 0.49	1.35	0.84, 2.15	0.54	0.33, 0.83
3b. Exposure rate
	Never Smokers		Smokers		Overall
	ERR/100 WLM	95%CI	ERR/100 WLM	95%CI	ERR/100 WLM	95%CI
<5 WL	0.35	0.01, 0.91	1.73	1.08, 2.66	0.76	0.49, 1.14

3c. Windows of time since exposure
	Never Smokers		Smokers		Overall

25+	0.14	−0.07, 0.58	1.05	0.49, 1.87	0.43	0.19, 0.74

^{^}All models adjusted for age, birth cohort, and smoking. Reported estimates for never smoker and smoker estimates were obtained by including interaction terms between smoking status and radon exposure. Radon exposure is lagged 5 years

^*Table estimates use weighted bootstrapping approach. Standard PROC NLMIXED results were −1.39 (95%CI −4.00, 1.21)

^**Table estimates use weighted bootstrapping approach. PROC NLMIXED results were 4.78 (95%CI 0.18, 9.37)
