Figure 3.
Waterfall-plots illustrating the distribution of RNF43 (a) and LRP1B (b) immunostaining among 446 patients. The waterfall plots show case-by-case the results of immunohistochemistry (RNF43-IHC and LRP1B-IHC; linear data presentation). The different colours illustrate the different staining intensities: RNF43-IHC 0 (blue), RNF43-IHC 1+ (light green) and RNF43-IHC 2+ (medium green) as well as LRP1B-IHC 0 (blue), LRP1B-IHC 1+ (light green), LRP1B-IHC 2+ (medium green) and LRP1B-IHC 3+ (dark green). The sum total of all staining intensities found in a single case always added to a total H-score of 100% according to the following formulas: P (RNF43-IHC 0) + P (RNF43-IHC 1+) + P (RNF43-IHC 2+) = 100% and P (LRP1B-IHC 0) + P (LRP1B-IHC 1 +) + P (LRP1B-IHC 2+) + P (LRP1B-IHC 3+) = 100%.
