Comparison of the sensitivity and specificity for predicting PFS and OS of AGC patients with cIS1 and cIS2 systems. a ROC curves displayed the significant predictive values of both systems for PFS prediction, and cIS2 system was superior to cIS1 system in PFS prediction. b ROC curves indicated the difference between the two systems was insignificant for OS prediction. cIS = circulating immune score
