DSG2 and adenoma: Very strong correlation was found in Dsg-2 staining expression between controls and adenomas (Kendall’s τ-c = 0.987, p < 0.001; Spearman’s ρ = 1, p < 0.001; Table 4) and between controls and malignancies (Kendall’s τ-c = 0.995, p < 0.001; Spearman’s ρ = 0.950, p < 0.001; Table 4).
