Estimates show the adjusted OR for each variable. ORs show the effect of each variable at the initial wave (Wave one or Wave 2) in predicting whether a respondent quit tobacco by the following wave (Waves 2 and 3 respectively). Covariates included state, living in an urban/ rural area, sex, age, marital status, socioeconomic status, attempts to quit in past year, intentions to quit, wave effects dependence, LII and LII*wave interactions.
