Heterogeneity of immune infiltration between two risk groups. (A) Violin plot visualizing the abundance of 22 immune cells between high and low-risk groups in 3 HCC cohorts. (B) Analysis of the correlation between PCDI and infiltration levels of M2 macrophages, Tregs and CD8 + T cells (C) Higher M2 macrophages infiltration weas associated to worse prognosis in HCC.
