(A–D) Combined effect survival analysis for OS on the basis of CCR1, CCR5 and CCR7; (E) nomogram; (F–H) verification model for nomogram in 1-, 2- and 3-year OS respectively; (I) risk score plot; (J) survival status scatter plot; (K) heat map of the levels of expression of CCR1, CCR5 and CCR7 in low- and high-risk groups; (L) Kaplan-Meier curves for low- and high-risk groups; (M) receiver operating characteristic curve for predicting 1-, 2- and 3-year survival in HCC patients by risk score.
