This table lists the median values indicated by the box plots in Figs 4 to 7. Where applicable, the table additionally lists the associated median p-value of Spearman rank correlations as well as the z-value and p-value of a left-tailed sign test testing the distribution of rank correlation p-values for a median of α = 0.05. Background colours as in Table 1.
