To examine the relationship between the treatment effect on ORR and OS, the difference between the ORR of the two treatment arms was plotted against log OS hazard ratio (Figure 3A). Like the corresponding PFS data, the resultant scatter plot showed a positive correlation.

WebApr 1, 2016 · The correlation between PFS and OS is stronger than that between ORR and OS. Other results suggest that the HR for the PFS/OS association is statistically significant (β = 0.5366, 95%CI: 0.3479–0.7253). Although the statistical benefit in PFS is likely contained in OS, the treatment effect in OS is generally diluted. WebNo significant differences in ORR were observed between the PD1 and PD1 +CTLA4 groups (35 % vs. 36 %; P = 0.67) or PFS and OS (median PFS 6.1 months vs. 8.5 months; P = 0.46, median OS 28.1 months vs. not reached; P = 0.59). Multivariate survival analysis revealed that PD1 +CTLA4 did not prolong the PFS and OS.
