Clinicopathological Features. Clinico-pathological features for the three cohorts examined. Age was analysed using Analysis of Variance (ANOVA), other parameters using Pearson’s Chi-Squared test. Group classification of patients by axillary procedure: group 1: primary axillary clearance; group 2: SLNB and dALND; group 3: SLNB and iALND.
