Table 3. Whole-brain functional connectivity network measures.
The BD group global network organisation did not differ from that of controls across all whole-brain network measures. Specifically, there was no main effect of (a) diagnosis (F(7,86)=1.863, p=0.086), (b) gender (F(7,86)=0.770, p=0.614), or (c) interaction between gender and diagnosis (F(7,86)=1.636, p=0.136) in BD relative to controls. MANCOVA, *p<0.05.
