Influence of sampling method on the biomarker read-out of VEGF family members. n-Fold induction levels in carcinoma samples of VEGF-A (A), VEGF-B (B), VEGF-C (C), VEGF-D (D) and PlGF (E) are shown. The n-fold induction value represents the ratio of the expression value of the carcinoma sample against the expression value of the paired healthy sample. The box represents the median with interquartile range and the whiskers represent minimum and maximum ratios. ns: not significant; *:pā€‰<ā€‰0.05; ***: pā€‰<ā€‰0.001 with Wilcoxon signed-rank test.
