Table III. Semi-quantitative analysis of S100A8/A9 Immunostaining.

Mean semiquantitative scores of S100A8/A9 staining in epithelium, glands, and subepithelial stroma

The difference between the groups is displayed in the Kruskal-Wallis ANOVA on ranks. The p values in italics reflect post hoc comparison with normal samples, with statistically significant values in bold. S100A8/A9 staining was significantly decreased in epithelium, glands, and subepithelial stroma in polyp tissue compared with normal samples. Among the groups, polyp tissue showed the least staining in all areas.
