Patient and tumour characteristics by Consensus Molecular Subtype (CMS) given as percentages. N, total number of patients per group; P-value* is derived from analysis of classified tumours only and a P-value of < 0.05 is considered significant; y years, F Female, M Male; a Post-operative Tumour-Node-Metastasis staging
