Cigarette smokers (current and past) and nonsmokers were compared using Fisher\u2019s Exact test for categorical variables and Mann\u2013Whitney test for continuous variables. Effects of cigarette smoking and smoking cessation on BO risk was assessed by stepwise logistic regression analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 1056 patients were included in the analysis [mean age: 57.2\u2009\u00b1\u200912.7years, Caucasian 880 (83.3%), male 985 (93.3%), and mean BMI 29.6 (SD:\u2009\u00b1\u20095.6)]. 827 (78.3%) were smokers and 229 (21.6%) were nonsmokers. 474 subjects (44.9%) had a previous history of smoking.

Higher smoking burden (pack years) was associated with higher risk of BO in this GORD cohort (<jats:italic>p<\/jats:italic> for trend\u2009&lt;\u20090.01).
