| Secondary | Continuous Abstinence Rates for Those Who Made Quit Attempts | 7-months post enrollment | Not smoking since the quit date |
| Secondary | 7-day Prevalence. | 7-months post enrollment | Seven-day point prevalence abstinence is a measure of, in this case, tobacco cessation outcomes for quitlines.
