Fig. 1. — Mortality risk of metastatic breast cancer (MBC) patients. (A) Kaplan-Meier survival curves estimate case fatality rate of MBC patients: the 1-, 3-, and 5-year fatality rate were 14.5%, 46.5%, and 60.8%, respectively. (B) Analysis of trend of fatality rate per month by Joinpoint regression: the joinpoint of lines was located at 13-18 (95% confidence interval [CI], [13-18] to [25-30]); trend 1 of fatality rate ranged from 0 to 18th month (annual percentage change [APC], 21.6; 95% CI, 1.0 to 46.3; p < 0.05); trend 2 of fatality rate ranges from 19th to 60th month (APC, –4.5; 95% CI, –8.2 to –0.7; p < 0.05).
