  1. EGD Esophagogastroduodenoscopy; SD Standard deviation
  2. The P-value is based on the Kruskal Wallis test. Significance is at the 5% level. Post hoc pairwise comparisons were performed using the Mann-Whitney U test with Bonferroni correction. Different letters indicate a significant difference at the 0.00833 (0.05/6) level
