Table 4 Mann–Whitney test between genes that do not show signals of population differentiation (Group 1, 47 genes) and genes that show signatures of population differentiation (Group 2, 10 genes), for each of the node centrality measured

From: Distribution of events of positive selection and population differentiation in a metabolic pathway: the case of asparagine N-glycosylation

  1. A p-value < 0.05 for a centrality measure would indicate that genes belonging to the two groups have different values for that centrality measure. Only Eccentricity remains marginally significant after a Bonferroni correction is applied.
