Association between episodic memory and GABA+ concentration by sex. GABA+ concentration was standardized into z-scores. Lines show the relation between GABA+ levels and episodic memory performance by (A) ApoE ε4 and (B) Sex. Linear regression models were constructed using the proportion of the TBR words (those words that participants were instructed to remember) as the dependent variable, and while accounting for the interactions of ApoE ε4 × GABA+ level and of sex × GABA+ level in separate models. Values represent regression coefficients β, their 95% confidence intervals (CIs), and the p-values of the standardized GABA main effects.
