PFS, progression-free survival; CI, confidence interval; HR, hazard ratio; ORR, objective response rate; DCR, disease control rate.†The ORR/DCR comparison between groups (positive vs. triple negative) was analyzed with Fisher’s exact test. ‡The 95% CI of the ORR/DCR was calculated with the Clopper-Pearson method. §The comparison of progression-free survival between 2 groups (hormone receptor positive vs. hormone receptor negative) was performed with a log-rank test. The HR and 95% CI (hormone receptor positive vs. hormone receptor negative) were estimated with the Cox proportional-hazards model.
