Objective: To validate the application value of Kyoto gastritis score in diagnosing Helicobacter pylori (Hp) infection status under gastroscopy in Chinses population, and to construct a modified prediction model to improve the diagnostic value of Hp infection. Methods: A total of 749 cases who underwent gastroscopy at the Digestive Endoscopy Center of the Ninth People's Hospital (North), Shanghai Jiao Tong University School of Medicine, from January 1, 2021 to June 1, 2023 were retrospectively collected. Patients were divided into Hp-positive group and Hp-negative group based on histopathological biopsy or 13C breath test results. The endoscopic mucosal manifestations were recorded according to the Kyoto classification of gastritis, including atrophy, intestinal metaplasia, fold enlargement, diffuse redness, nodularity, RAC, red streak, and other 18 manifestations to verify the diagnostic value of Kyoto gastritis score for Hp infection. The mucosal manifestations with significant differences in univariate ana
