Results of the Kruskal-Wallis (K-W) test in the analysis of the topology-dependent length of a hydrogen bond between a non-halogenated ligand (LH) and a protein: for each pair of hydrogen bond acceptor/donor pair the p-value for the null hypothesis that both distributions are identical was estimate

The values marked in red denote the pairs of distributions that differ one from the other, with α = 0.05. Additionally, the identified number of each type of hydrogen bond, n, and mean rank test are presented.
