AOR = adjusted odds ratio; OMSC = Ottawa Model for Smoking Cessation; post = postassessment; pre = preassessment.
a
Controlling for clinic-level variance between clusters, patient sex, patient education, and self-reported anxiety or depression; based on inclusion of 15 clinics unless otherwise indicated.
b
P value based on Wald statistic.
c
The estimated G matrix for clinic-level variance was not a definite positive, so clinic-level variance was not included in this model.
