A SIRPB1 expression in 33 tumor types vs. controls; Wilcoxon test. B Forest plot of SIRPB1's prognostic value in TCGA tumor types. C Kaplan–Meier curves for OS and PFI. D SIRPB1 levels in normal vs. glioma tissues; Wilcoxon test. E ROC curve for SIRPB1's diagnostic accuracy in gliomas; x-axis: FPR, y-axis: TPR. F Immunohistochemical staining of SIRPB1 in normal and glioma brain tissues and (G) statistical analysis. H Kaplan–Meier curves for OS of glioma patients in First Hospital of Jilin University. I Western blot of SIRPB1 in paracancerous (P) and glioma (T) brain tissues. Significance: ns: P ≥ 0.05, *P < 0.05, **P < 0.01, ***P < 0.001
