Immunotherapy response and the combined scoring of CHAF1A with classic biomarkers in gastric cancer. A: The ROC curves for response prediction by CHAF1A expression, classic biomarkers, and their pairwise combinations. B: Objective response rate (ORR) according to the combined scoring of CHAF1A with classic biomarkers. C: The ROC curve for response prediction by the combined scoring of all biomarkers. D: ORR according to the combined scoring of all biomarkers. ROC receiver operating characteristic curve, AUC the areas under the ROC curves, CS combined scoring, MSI microsatellite instability, TMB tumor mutation burden, CPS1 or CPS5 combined positive score of PD-L1 with a cutoff value of 1 or 5; S0, S1 and S2: score 0, 1 and 2
