The p-values, U statistics, and z-scores correspond to two-sided Mann–Whitney U tests assessing whether NI is different between the two groups at a given node. The p-values were corrected using the Bonferroni–Holm procedure, and none is significant. The effect size (median difference of NI) and confidence intervals further show that there are no statistical differences between the groups in any of these nodes.
