Results of generalized estimating equations analyses predicting smoking prevalence and treatment engagement among patients in cancer clinics that used the module and cancer clinics that did not use the module adjusting for the clustering of patients within clinics.

* For patients without smoking status assessment, if they received any smoking cessation treatment, they would be identified as smokers. Therefore, smoking prevalence in cancer clinics that used the module and cancer clinics that did not use the module were calculated for patients who were assessed and documented as smokers or received any type of smoking cessation treatment (n = 35,548). **Any treatment is defined as patients receiving medication, brief advice given, or additional counseling was referred. *** Since there were no patients referred for additional counseling in cancer clinics that use the module, we could not get an estimate for this indicator of treatment engagement.
