Figure 3 Progression-free survival of palbociclib plus endocrine therapy stratified by patient characteristics. (A) Number of metastatic sites; (B) Whether or not receiving chemotherapy for MBC; (C) Line of palbociclib in ET; (D) response to the most recent ET; (E) Type of combined ET; (F) Palbociclib combined with prior ET or unused ET. Survival curves of PFS were plotted by the Kaplan-Meier method and compared by the log-rank test. P-values of less than 0.05 indicate statistical significance. PFS – progression-free survival; ET – endocrine therapy; MBC – metastatic breast cancer; SERD – selective estrogen receptor degrader; AI – aromatase inhibitor; SERM – selective estrogen receptor modulator.
