Table 5 Results of the Wilcoxon test, t-test and the average plot for the selected differentially expressed genes. Verification of the consecutive sampling and coincidence test by comparison to the Wilcoxon test (P = 0.03), t-test at the level of 0.001 and 0.01 and the and plot of average values. The first five rows of data show the numbers of genes satisfying a given test and the last four the number of genes selected by the coincidence test, which also satisfied a particular second criterion
