Table A2.

Unadjusted multiplicative p-values ^a associated with interaction terms between quitline exposure variables and sociodemographic variables for 90-day smoking cessation in the sample of year-ago smokers who had made a quit attempt.

	Budget per Smoker	Reach	Counseling Sessions	Hours of Counseling
Sex	0.029 *	0.629	0.634	0.587
Race/ethnicity	0.595	0.285	0.079	0.506
Education	0.247	0.213	0.053	0.010
Family income	0.974	0.381	0.644	0.065

Note. Each interaction is estimated from a separate model with all main effects and a single interaction term between quitline exposure and either sex, race/ethnicity, education, or income variable. All models controlled for age, age², sex, race/ethnicity, education, family income, state-level cigarette price, state-level smoke-free laws, with fixed year and random state effects. ^a p values were obtained from testing multiplicative interactions and are unadjusted for multiple comparisons. Boldface numbers indicate statistically significant interactions (p < 0.05) after adjusting for multiple testing. Numbers with * were statistically significant (p < 0.05) prior to multiple testing, but not after.
