(A) Significant positive correlation between Hill grade and acid exposure index. (B) Significant positive correlation between the Hill grade and bolus exposure index. (C) Significant positive correlation between Hill grade and number of reflux episodes. (D) Significant positive correlation between Hill grade and number of gastroesophageal refluxes (GER) reaching the proximal extent. Statistical analysis was performed using the Kruskal-Wallis test.
