Without capecitabine, the PFS was 9.30 months for HER2-zero and 7.95 months for HER2-low, a near-significant difference (p=0.067, HR 0.821, 95% CI 0.665-1.014, Figure 5D ).

Variations were observed in PFS among different patterns of HER2 evolution during 1st-2nd line endocrine therapy; however, these differences did not reach statistical significance (HER2-zero to HER2-zero vs.
