Fig. 4From: CXCR2–CXCL1 axis is correlated with neutrophil infiltration and predicts a poor prognosis in hepatocellular carcinomaPrognostic significance of the combined actions of CXCR2 and CXCL1 expression in association with RFS and OS. Kaplan–Meier curves illustrate the duration of RFS and OS according to the combination of CXCR2 and CXCL1 expression in non-tumoral (a), peri-tumoral stroma (b) and intra-tumoral (c) regions; *, P <0.05; **, P <0.01; ***, P <0.001Back to article page
