Figure 1

Bax expression in gastric mucosa in healthy controls (HCs) and GERD patients, in relation to BRI status. Grouped data are presented in 100% display stacked columns for each grade (n; %). According to the percentages of the stained epithelial cells, the immunohistological sections were scored and graded as follows: 0 = absence of staining, 1 = staining up to 5%, 2 = staining >5%-10%, 3 = staining >10%-25%, 4 = staining >25%-50%, and 5 = staining >51%.
