Association between abdominal symptoms and gastric body redness in Linked Color Imaging in patients without Helicobacter pylori infection

Background: To investigate the association between abdominal symptoms and redness in Linked Color Imaging (LCI) in patients without Helicobacter pylori infection. Methods: Consecutive patients without H. pylori who underwent esophagogastroduodenoscopy using LCI between April 2017 and December 2019 with a patient's profile and symptom questionnaire (Izumo scale, Frequency Scale for Symptoms of Gastroesophageal Reflux Disease [FSSG] score) were selected retrospectively.
