In our study, the analysis of BCSS ( Supplementary Figure ) or DFS of HR+ HER− patients did not seem to be affected by the PR status (cutoff 20% ( Prat et al , 2013 )); however, in the discrepant group patients with PR ⩾20% had almost significantly better BCSS (HR=0.50, 95% CI (0.15–1.06), log-rank P =0.06).
