Note: F = F statistic (numerator and denominator degrees of freedom are 1 and 360, respectively, for all outcomes); adj.p = p-value adjusted for false discovery rate; vol = volume (ml); GM = grey matter. Bold denotes p-values that remained statistically significant after false discovery rate adjustment (p < 0.05)
