↵* Values represent the proportion (95% confidence interval) of patients who were abstinent in each group.
↵† Abstinence (yes/no) was regressed in the treatment group and for the following covariates in logistic regression models: patient age, sex, education, comorbid anxiety, depression, posttraumatic stress disorder, number of cigarettes smoked per day at baseline, model of change category, and perceived stress scale score. Values are shown as odds ratio (95% confidence interval) estimates and represent the odds of abstinence in the auriculotherapy group compared with the control group.
