Estimates of Flavor and Nicotine Effects on Appeal, by Use of e-Cigarettes as a Quit-smoking Aid

	Use e-cigarettes as a quit-smoking aid				Difference in effect estimates, by use of e-cigarettes as quit-smoking aida
	Yes (N = 31)		No (N = 12)
	B (SE)	p	B (SE)	p	p
Flavor and Nicotine main effects
Fruit vs Tobacco flavor	10.96 (1.97)	<.001	13.77 (2.52)	<.001	.29
Menthol vs Tobacco flavor	4.36 (2.36)	.06	11.29 (3.02)	<.001	.83
Nicotine-containing vs Nicotine-free	−8.57 (1.57)	<.001	−13.50 (1.99)	<.001	.16
Flavor × nicotine interaction effects
Fruit vs Tobacco × Nicotine vs Nicotine-free	1.18 (3.89)	.76	12.69 (4.87)	.01	.05
Menthol vs Tobacco × Nicotine vs Nicotine-free	7.79 (4.65)	.09	20.29 (5.82)	.001	.06

Note.

Nicotine = 6 mg/mL; Nicotine-Free = 0 mg/mL. Appeal = Average of “liking,” “willingness-to-use-again” and “disliking” (reverse-scored) (range 0–100). B(SE) = Effect Estimate and Standard Error of Effect Estimate.

^aTest of interaction between use of e-cigarettes as a quit-smoking aid (yes vs no) and respective flavor, nicotine, or flavor × nicotine interaction effect adjusted by interaction between menthol combustible cigarette use and respective flavor, nicotine, or flavor × nicotine interaction effect.
