a, Kaplan-Meier curves of PFS for arm B by age group.
Age >60yr, N = 17 versus age ≤60yr,
N = 21. PFS2 denotes the PFS of the WINTHER treatment.
P = 0.0361 by two-sided log-rank test. b,
Kaplan-Meier curves of PFS for arm B by sex. Sex = female,
N = 12 versus sex = male, N= 26. PFS2
denotes the PFS of the WINTHER treatment. P = 0.0252 by
two-sided log-rank test. c, Kaplan-Meier curves of PFS for arm
B by the number of previous treatments. For the number of previous
treatments of ≤2, N = 11 versus >2,
N = 27. PFS2 denotes the PFS of the WINTHER treatment.
P = 0.0066 by two-sided log-rank test.
