Risk factors for low response to proton-pump inhibitor treatment in reflux esophagitis and non-erosive reflux disease evaluated by the frequency scale for the symptoms of gastroesophageal reflux disease

摘要

This study aimed to evaluate risk factors for resistance to proton-pump inhibitor (PPI) therapy among patients with reflux esophagitis (RE) and nonerosive reflux disease (NERD) in gastroesophageal reflux disease (GERD) using a standardized questionnaire in Japan: the Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease (FSSG).
