Overall (a–c) and progression-free (d–f) survival probabilities estimated through multivariable Cox regression analysis in 56 patients of Pembro cohort stratified according to biomarker median values: sPD-L1 = 24.2 pg/mL (a,d); sB7-H3 = 0.5 ng/mL (b,e); sB7-H4 = 63.9 pg/mL (c,f). Legend—HR: hazard rate ratio adjusted for gender, age, cycles of therapy, ECOG-PS and histotype; 95% CL: 95% confidence limits for HR.
