Table 1 contains mean and frequency data summarizing the demographic and smoking characteristics of the sample. The sample was compared, by assigned treatment regimen, on baseline measures of age, number of daily cigarettes smoked, expired carbon monoxide (CO), body mass index (BMI), CES-D, and the FTND using univariate ANOVA, but no significant differences were found. Additionally, no significant differences were found when the sample was compared by gender on these same characteristics. The categorical variables (gender, ethnicity/race, employment, and education) were compared using chi-square tests, but none differed by treatment regimen.
