Figure 2. The constructed immune risk signature was linked with OS prognosis. Kaplan-Meier survival curves according to distinct immune signature subgroups in (A) the TARGET discovery cohort, (C) GSE21257 cohort, and (E) TCGA sarcoma cohort. (B, D, F) Forest plot representation of the multivariate Cox regression models delineated the connection between immune risk signature and prognosis in the three datasets. Clinical confounding factors were taken into consideration.
