Table A4.

Unadjusted multiplicative p-values ^a associated with interaction terms between quitline exposure variables and sociodemographic variables for 30-day smoking cessation.

	Budget per Smoker	Reach	Counseling Sessions	Hours of Counseling
Sex	0.039 *	0.537	0.830	0.307
Race/ethnicity	0.982	0.451	0.088	0.828
Education	0.072	0.072	0.060	0.081
Family income	0.914	0.508	0.424	0.138

Note. Numbers with * were statistically significant (p < 0.05) prior to multiple testing, but not after. 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.
