Fig. 3: Clinical utility of the COMB-Radscore.

Kaplan-Meier analysis of PFS (a) and OS (b) for the low and high COMB-Radscore groups in the training (left) and testing (right) cohorts. c Proportional composition of different patient responses between the low and high COMB-Radscore groups in the training (left) and testing (right) cohorts. HR hazard ratio, CI confidence interval, PFS progression-free survival, OS overall survival, CR complete response, PR partial response, SD stable disease, PD progressive disease. The definitions of CR, PR, SD, and PD were based on the RECIST V.1.1 criteria.
