Denotes context variables that are significant after a Holm correction for familywise type 1 error (Holm, 1979).

Conducted using logistic regression

Excludes individuals who did not achieve initial abstinence

Conducted using proportional hazards survival analysis

Excludes individuals who did not lapse

Results do not include interaction with treatment period
