Kaplan-Meier plots of BCSS and overall survival for concentrations of active tamoxifen metabolites. Patients are grouped according to concentrations of active metabolites as indicated by colored lines. Time starting at 3 years after surgery. a,b BCSS for Z-4OHtam and Z-endoxifen at concentrations above and below 3.26 nM and 9.00 nM, respectively. c,d BCSS for Z-4OHtam and Z-endoxifen at three serum concentrations: low, intermediate, and high levels, as shown in the figure. e,f Overall survival for Z-4OHtam and Z-endoxifen at the same three concentrations as shown in c and d.
