Table 3. Relationship between FA values and remission in multivariate models.

Regional FA value	Estimate	SE	Test Result (Z-score)	p value
SFG, left	0.0099	0.0036	2.72	0.0064
SFG, right	0.0068	0.0030	2.25	0.0244
MFG, left	0.0007	0.0032	0.20	0.8405
MFG, right	0.0050	0.0043	1.16	0.2476
ACC, left	0.0079	0.0036	2.18	0.0290
ACC, right	0.0088	0.0036	2.42	0.0156

FA = fractional anisotropy; SFG = superior frontal gyrus; MFG = middle frontal gyrus; ACC = anterior cingulate cortex; CC = corpus callosum. Models examined remission of depression as the dependent variable, with FA, age, sex, baseline depression severity and medical comorbidity as independent variables.
