Comparison of network properties between the low- and medium- risk group. Vertical axis indicated sample size; Horizontal axis indicated proportion of p-values < 0.05; Maximum of difference, maximum difference across network structure of two subgroups; Difference in global strength, difference for the overall level of connectivity across two subgroups’ networks; Difference in edge strength, difference in individual edges across two subgroups’ networks; c(26,27) represents the edge weight between node “SOI1 (My family life is affected because of illness.)” and node “SOI2 (Social activities are affected because of illness.)”. c(28,29) represents the edge weight between node “SOA1 (My relatives and friends give me material help and support.)” and node “SOA2 (My neighbors and friends all care about my illness.)”. c(15,16) represents the edge weight between node “PAI1 (I moan because of pain.)” and node “PAI2 (I can’t concentrate on things because of pain.)”
