First-order, second-order, and third-order nodes are defined by the length of the newly formed or severed link. Bold font indicates the cases where (i) the proportion of positive log growth rate of nodes is higher for newly formed links than severed links or (ii) the proportion of negative log growth rate of nodes is higher for severed links than newly formed links in a given year
