Boxplot of the tumor reduction rate in the hepatobiliary phase in comparison to immunostaining results of OATP1B3. Tumor reduction rate between the plain and hepatobiliary phases in comparison to the percentage of positive cells (a), the intensity of staining (b) and the resulting immunoreactive score (c, multiplication of a and b). Data presented as box plots follow standard Tukey representations. The Kruskal–Wallis test was used to compare the groups.
