Fig. 4: Direct cytotoxicity and ADCC by pCR status.

Paired pre- and post-treatment direct cytotoxicity levels of patient PBMCs against a K562 and b SKBR3 by pCR. The K562 dataset lost a paired pCR sample due to a technical issue acquiring the sample. c Pre- and post-treatment trastuzumab-mediated ADCC against SKBR3 by patient PBMCs by pCR. A paired Student’s t test was used to determine statistical significance. All p values were adjusted for multiple testing. NS not significant.
