Background/Aims: Gastroesophageal reflux disease is one of the most common causes of chronic cough and is a potential risk factor for the exacerbation of chronic obstructive pulmonary disease (COPD). The aim of this study was to investigate the prevalence and risk factors for reflux esophagitis (RE) in COPD patients. Methods: From our hospital database, between September 2006 and April 2010, we searched for subjects who were 40 years old or older and had undergone both postbronchodilator spirometry and esophagogastroduodenoscopy (EGD). COPD was defined as having a ratio of forced expiratory volume in 1 second to forced vital capacity
