Kaplan-Meier curves for relapse-free survival (RFS) and overall survival (OS) in the intention-to-treat (ITT) population. (A) Kaplan-Meier estimates of RFS at 7 years by treatment arm in the ITT population, showing a significant benefit of THL (paclitaxel, trastuzumab, and lapatinib) versus TH (paclitaxel plus trastuzumab) treatment arms. (B) Kaplan-Meier estimates of OS at 7 years by treatment arm in the ITT population, showing a significant benefit of THL versus TH treatment arms. (C) Kaplan-Meier estimates of RFS at 7 years by pathologic complete response (pCR) status in the ITT population, showing a significant improvement in outcome in pCR versus residual disease (RD). (D) Kaplan-Meier estimates of OS at 7 years by pCR status in the ITT population, showing a significant improvement in outcome in pCR versus RD. HR, hazard ratio; TL, paclitaxel and lapatinib.
