Unless denoted by an asterisk (*), cells show p-values for Dunn’s post-hoc test following a significant Kruskal-Wallis (K-W) test for each subfield or DTI parameter. Asterisks (*) denote p-values calculated from ANOVA with Tukey’s post-hoc, as data in all three groups were normally distributed. Where K-W test was not significant, pairwise comparisons were not conducted. Bold values indicate P<0.05. Key: Abbreviations as defined in the text, Vols = volumes; Total HC = total hippocampal volume
