Table 2. Endogenous connections weighted by Bayesian model average in high suicide risk group (HSR), low suicide risk group (LSR) and healthy controls group (HC).

Endogenous connections	HSR	LSR	HC	All groupscombined (p-values)	GroupComparisons (p-values)
				Endogenous connections	Endogenous connections
MPFC→PCC	0.13(0.10)	0.06(0.05)	0.78(0.17)	<0.001*	<0.001*
PCC→MPFC	0.62(0.13)	0.64(0.15)	0.28(0.15)	<0.001*	<0.001*

Group mean estimates and SD (in brackets) are reported for endogenous connections which was weighted by Bayesian model average, the endogenous connections of all groups combined means that were significantly greater than zero across the three groups. We also report the group differences, which were identified using a series of ANOVAs. PCC = posterior cingulate cortex; MPFC = medial prefrontal cortex; “*” means significant statistical difference (statistical threshold p<0.05).
