Survival curves of HCC patients stratified by B7-H3 (CD276) or CD47 expression levels in TCGA-LIHC cohort. HCC patients (n = 345) were divided into high or low expression group based on the median value of gene expression. (A) Survival curves of HCC patients with high and low B7-H3 expressions. (B) Survival curves of HCC patients with high and low CD47 expressions. The P-value cut-off was 0.05 (log rank test).
