Fig. 2From: Somatostatin and CXCR4 chemokine receptor expression in hepatocellular and cholangiocellular carcinomas: tumor capillaries as promising targetsDifferential somatostatin receptor (SSTR) and CXCR4 expression in hepatocellular and cholangiocellular carcinomas. Box plots of the expression levels (IRS values) of SSTRs and CXCR4 in hepatocellular and cholangiocellular carcinomas. Depicted are median values, upper and lower quartiles, minimum and maximum values, as well as outliers. Outliers are defined as follows: circles: mild outliers; data that fall between 1.5 and 3 times above the upper quartile or below the lower quartile; asterisks: extreme outliers; data that fall more than 3 times above the upper quartile or below the lower quartileBack to article page
