Immune checkpoint expression. (a) Correlation of risk scores with the expression of 22 immune checkpoints. (b) Differential immune checkpoints between groups. (c–f) Scatter plots show the correlation of risk scores with the expression of TNFSF4 (c), CD44 (d), CD40 (e), and PDCD1 (f). Survival analysis based on the signature combined with the expression of TNFSF4 (g, h), CD44 (i, j), CD40 (k, l), and PDCD1 (m, n). ; .
