†All estimates adjusted for age, race, educational status, and baseline cigarette consumption. For the seven day analysis, eight respondents were excluded for missing data on covariates, and seven were excluded as they had quit for less than seven days. For the 90 day analysis, eight respondents were excluded for missing data, and 23 were excluded as they had quit for less than 90 days.
‡Interaction for seven day quits, p  =  0.05.
