Tumour stages for patients with different tumour epithelial ERBb2-AR and AR-IR scores.

Values shown for the tumour stage are the number of cases, with the percentage of the total for the given ErbB2-IR/AR-IR group. Values shown for the Ki67 index are the median scores, with sample sizes and interquartile ranges in brackets. The divisions represent a median split of each parameter. AR-IR is given as the % of cells with nuclei staining positive for this receptor (see [15]). The P value was determined by a χ2 analysis of the data (for tumour stage) or by Kruskall-Wallis one way analysis of variance by ranks (for Ki-67 index).
