Correlation coefficients between neurometabolites measured from visual and posterior cingulate cortices

Location	GABA⁺and Glx	GABA⁺and tNAA	Glxand tNAA	ΔGABA⁺and ΔGlx	ΔGABA⁺and ΔtNAA	ΔGlxand ΔtNAA
VC	−0.16	0.33*	0.33*	0.06	0.10	−0.17
PCC	0.25***	0.50***	0.17*	0.03	−0.18*	0.04

Correlation coefficients are Pearson linear partial coefficients after controlling for the common reference neurometabolite tCr. All neurometabolites are referenced to tCr and are tissue corrected. PCC, Posterior cingulate cortex; VC, visual cortex.
*p < 0.05; ***p < 0.001.
