Robust = skipped correlation using Pearson product-moment r-value on data with bivariate outliers removed53. Out = number of bivariate outliers removed53. Degrees of freedom on the skipped correlation (n − 2 − Out). Control = partial correlation controlling for Sex, levels of PFC or VIS Glutamate (Glu/Cre), and PFC or VIS gray matter concentration (GM). Degrees of freedom on the Control partial correlation (n − 5 − Out). Bold entries and asterisks indicate significance at 95% boot-strapped confidence intervals
