Expression of CTNNB1 protein in IBC and nIBC specimens. A: The percentage of CTNNB1-positive and CTNNB1-negative cases in the validation series comprising 39 IBC and 80 nIBC specimens. B-C: Percentage quantification of CTNNB1 staining pattern detected on TMA validation series. The p-values reported in each graph were obtained by chi-square test with Yates’s correction for continuity between IBC and nIBC groups. D: CTNNB1 subcellular immunostaining pattern: membrane (M), membrane/cytoplasmic (M/C), nuclear/cytoplasmic (N/C) or negative (Neg).
