Figure 5. Cluster analysis of depression-like behavior at PND90.

PND90 FST data was examined using K-mean cluster analysis with IBM SPSS (IBM, Armonk, NY) (panel I). Two clusters were identified in cluster test at PND90 as a function of immobility time in FST (panel II). Control group n = 25; Resilient group n = 28; Susceptible group n = 27. (*) indicates significantly different from control as well as resilient groups at p < 0.05.
