Integrated tumor stromal features of hepatocellular carcinoma reveals two distinct subtypes with prognostic/predictive significance

Figure 5. (A) Representative immunohistochemistry images of the ten immune markers. The bars (150 μm and 20 μm) were shown in the upper left figures. (B) Associations of stromal type with the immune markers. According to the data distributions, the optimal cut-off values for OX40 and PD1 were selected to perform comparison between groups, positive PD-L1 tumor cells staining was defined as more than 1% tumors cells staining on the membrane of the tumor cells. The others were compared by continuous data.
