Prognostic analyses for sarcoma patients. a Forest plot showing the results of the univariate and multivariate Cox analyses for 18 IRGs that were incorporated into the signatures. Two overlapping genes are highlighted in red. b Circos plot showing the location of OS-related IRGs. From outside to inside: 23 chromosomes, significant IRGs in the univariate Cox analysis, HR value of corresponding IRGs in the univariate Cox analysis, IRGs incorporated into the OS signature, and gene–gene interactions. c Circos plot showing the location of PFS-related IRGs. From outside to inside: 23 chromosomes, significant IRGs in the univariate Cox analysis, HR value of corresponding IRGs in the univariate Cox analysis, IRGs incorporated into the PFS signature, and gene–gene interactions. IRGs Immune-related genes, OS Overall survival, PFS Progression-free survival
