Fig. 6: Identification of polarization marker for distinguishing HCC and ICC.

a It shows the logarithm scale density heat map for hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) samples, and two clusters are labeled, one with solid line (cluster 5) and one with dashed line (cluster 3). The box whisker plots for the two polarization markers are shown in (b) and (c), the box and the whiskers mark the 10, 25, 50, 75, and 90 percentiles, respectively.
