Table 8 Relative expression of mRNA levels in tumor samples after ex vivo exposure to cisplatin. The IC₅₀ concentrations for the samples tested are shown for each drug (median and range). The p values have been calculated using non-parametric statistics, in detail the Wilcoxon matched pairs test. On statistical advice, we chose not to use a Bonferroni's correction, but it should be noted that some technically statistically significant results could have arisen by chance.
