a using partial correlations with age, sex, and depression as covariates of no interest, shown are r-values (p-values in brackets, significant results indicated in bold, marginally significant results indicated in italics). Note: For uncinate fasciculus, amygdala, and hippocampus, results underlay hypothesis-driven tests; the remaining tests underlay the null hypothesis.
