The upper diagonal of the table shows Mann–Whitney U-test results (two-tailed significance levels obtained using Monte Carlo permutations), and the lower diagonal shows permutation tests of differences between group means (two-tailed significance levels obtained using 10,000 permutations). When a Bonferroni-corrected multiple comparisons is used, the significance level is 0.0033 for 15 comparisons; the P values below the threshold are marked in bold. Values tested are from Table S4.
