Participant disposition

Note: After treatment assignment, some participants did not participate in the behavioral interventions. A few who had participated did not set a target date to quit smoking, one of the required steps to initiate the varenicline prescription.

* Not attempted: Because the timing for interviews was based on the target quit date, no attempt was made to contact participants at 3 months if they had not set a quit date (n=33). Other participants were not attempted for interviews if they had requested no further participation (n=16 at 3 months, n=48 at 6 months) or had passed away (n=1 at each time point).
