Tissue array immunohistochemical staining for Ron. (A) Comparison of Ron staining score in DCIS versus invasive cancer subtypes (p < 0.01, Mann-Whitney test, n = 250). (B) Comparison of Ron staining score among T-stage (Tis = carcinoma in situ, T1 = tumor < 20 mm, T2 = tumor > 20 mm and < 50 mm and T3/4 = tumor > 50 mm). Tis versus T1, and T2 versus T3/4 did not reach statistical significance, but all other pairwise comparisons had p-values < 0.05 by Kruskal-Wallis test followed by Dunn's multiple comparisons (n = 250).
