Centrality index of nodal strength. (A) The depressive symptom and non-depressive symptom groups at baseline (DS-t1 and NDS-t1). (B) The depressive symptom and non-depressive symptom groups at t2 (DS-t2 and NDS-t2). (C) The depressive symptom and non-depressive symptom groups at t3 (DS-t3 and NDS-t3). (D) The depressive symptom and non-depressive symptom groups at t4 (DS-t4 and NDS-t4). The centrality index is shown as standardized z scores.
