- aAdjusted effect estimates obtained from ordinary least squares regression (visit attendance), Poisson regression (counseling attendance), or repeated measures linear regression with generalized estimating equations (nicotine patch use and quit attempts), each controlling for age, gender, race, drug use severity, alcohol use severity, psychiatric symptom severity, nicotine dependence, and treatment assignment
- *P < 0.05 for comparison to reference group (none)
