Kaplan–Meier survival curves between HPN high- and low-expressing groups in HCC based on immune cell subgroups. Low HPN level in enriched B cells (a), CD4 + memory T cells (b), CD8 + T cells (c), NK T cells (e), Treg cells (f), Th1 cells (g) and Th2 cells (h) is correlated with worse OS in HCC. For the enriched macrophages, low HPN level showed a decreasing trend in OS, though it did not reach statistical significance. HCC hepatocellular carcinoma
