Regression Model Testing Main and Interactive Effects of Virtual Reality Enclosed Display and Graphic Health Warning Sign on Urge to Smoke and Tobacco Purchase Attempts Among Current Smokers and Recent Quitters: United States, December 2011–January 2012

	Urge to Smoke		Tobacco Purchase Attempts
Covariate	Current Smokers (n = 712), B (95% CI; SE)	Recent Quitters (n = 465), B (95% CI; SE)	Current Smokers (n = 712), AOR (95% CI)	Recent Quitters (n = 146), AOR (95% CI)
Main effect: enclosed display	−7.05* (−13.20, −0.91; 3.13)	−6.00** (−11.00, −1.00; 2.54)	0.06** (0.03, 0.11)	...
Main effect: GHWS	−0.14 (–7.44, 7.17; 3.72)	−1.26 (–7.01, 4.49; 2.92)	0.70 (0.41, 1.22)	0.81 (0.20, 3.33)
Interaction: enclosed display × GHWS	0.66 (−8.23, 9.56; 4.53)	0.71 (−6.33, 7.76; 3.58)	1.01 (0.42, 2.41)	...

Note. AOR = adjusted odds ratio; CI = confidence interval; GHWS = graphic health warning sign. Enclosed display incorporated all enclosed-display conditions (C2, C3, C5, C6). All regression models were adjusted for age, race/ethnicity, gender, education, and frequency of going to a convenience store. Current smoker models also controlled for time since last cigarette, time from waking until first cigarette, quit attempt in past 12 months, and plans to quit in the next 30 days. Recent quitter models also controlled for time since last quit.
