Intent-to-Treat: (MTS = 105, Control = 91); Treatment Initiator Analysis: (MTS = 59, Control = 59).
Point Prevalent Abstinence: CO < 7ppm plus no cigarettes for last 7 days on TLFB.
Continuous Abstinence: CO < 7ppm plus no cigarettes on TLFB plus statement of no cigarettes since the Quit Day.
Odds Ratio (CI): Logistic regression exponentiated coefficients used to calculate OR with 95% confidence interval.
A
Odds Ratio: Adjusted Odds Ratios controlling for race, education level and cigarettes smoked per day.
