The Kaplan-Meier plots of DFS and OS.
(A) The median DFS was significantly longer in patients with ypN0 than ypN+ (105.9 vs 97.0 months, p = 0.007). (B) There was also significant difference in the median OS (110.8 vs 107.4 months, p = 0.007). Abbreviations: ypN0: No invasive residual in nodes, ypN+: invasive or noninvasive residuals in the breast, infiltrated lymph nodes.
