Note. Lower ORs indicate that higher scores on the CESD subscale predict reduced odds of abstinence OR=odds ratio of standardized scores (z-scores). OR=1.00 means nonsignificant effect. CI=Confidence Interval. CESD=Center for Epidemiologic Studies Depression Scale. FTND=Fagerström Test for Nicotine Dependence.

^aModel included all four CESD subscales simultaneously included as predictors.

^bModel included all four CESD subscales, FTND scores, cigarettes smoked per day, and past history of depression as predictors.
