Gini's mean difference and the long-term prognostic value of nodal quanta classes after pre-operative chemotherapy in advanced breast cancer: data and software

The file 311pat_9_anon-trim.xlsx provides all data and the R script gmdboot_01 is the full script to reproduce the figures and tables (and beyond) the paper:
