Patient demography and clinical histopathological findings of excised breast tumours are shown for each group and the entire cohort. Quantitative data are expressed as mean and standard deviation (apart from Nottingham Prognostic Index where median and interquartile range are shown), while qualitative data expressed as number of positive cases.
*Significant findings (p < 0.05) are marked.
