Results regarding users whose network centralities co-evolve with physical activities. a The number of users with co-evolution relationship for each of the 10 centralities individually (ECC to SMS_F) or by at least one of them (NET_PA). Red and blue portions of the given bar indicate users whose centralities are positively and negatively correlated with physical activities, respectively. b The number of users found by exactly k centralities (k=1,2,…,10). c The number of users that are unique to the given centrality, i.e., for a given user, only for this centrality, the user’s centrality values are significantly correlated with physical activities. d Pairwise overlaps between users with co-evolution relationship predicted by the different centralities. An overlap is measured as Jaccard index, and the resulting overlap size is indicated by the given color. The significance of the overlaps is computed by using the hypergeometric test. *, **, and *** indicate statistical significance at p-value thresholds of 0.05, 0.01, and 0.001, respectively
