Cancer beliefs and willingness to be screened for lung cancer

Characteristic	Never smokers	Former smokers	Current smokers	All subjects	Smokers v non-smokers
Characteristic	(n = 925)	(n = 517)	(n = 559)	(n = 2001)	Odds ratio* (95% confidence interval)
^†p<0.05 compared with non-smokers by t test or χ² test, as appropriate.
^‡p<0.05 compared with former smokers by t test or χ² test, as appropriate.
^§p<0.05 compared with non-smokers, after adjusting for age in a logistic regression model.
*Odds ratios reflect comparisons between smokers and non-smokers, and are adjusted for age in a logistic regression model.
