Figure 7.The principal components analysis (PCA). The high-risk group and low-risk group tended to express different immune status. PCA among high-risk group and low-risk group based on the immune-related risk gene sets (A). PCA among high-risk group and low-risk group based on the genome-wide expression sets (B). The results showed that the high-risk group and low-risk group were divided into two parts in immune-related risk gene sets.
