	Predicted probability of smoking cessation (95% CI)
	Intervention Group:	Comparison Group:
Full Sample	Age 18–64 Years	Age>65 years

Note: From the BRFSS; includes 25,738 adults age 18–64 (weighted n = 15,148,712) and 10,345 adults age>65 years (weighted n = 3,344,793) with incomes <100% of the federal poverty level who reported being a current or former smoker. Smoking cessation defined as having quit smoking within the prior year, but not having smoked any cigarettes for at least one month. Average predicted probabilities are derived from logistic regression models including an interaction term between Medicaid coverage and intervention group indicator (age 18–64 years). Analyses control for sex, education, race, state, year, and state cigarette taxes and clean indoor air laws. Bold type indicates results that are statistically significant at the p<0.05 level.
