Fig. 3From: The role of postmastectomy radiation in patients with ypN0 breast cancer after neoadjuvant chemotherapy: a meta-analysisMeta-analysis of relative risk (RR) for the correlation between PMRT and survival outcomes. A DFS in PMRT and no-PMRT group; B OS in PMRT and no-PMRT group. RR less than 1 represents a lower risk of progression or death. The analysis showed that patients with PMRT were no correlation with a difference in DFS and OS.
