Abbreviations: g×t – diagnostic group by scan time interaction, g×t×BA – diagnostic group by time by Brodmann’s area interaction, g×t×h×BA – diagnostic group by time by hemisphere by Brodmann’s area interaction, g×t×r×BA – diagnostic group by time by region by Brodmann’s area interaction, g×t×h×r×BA – diagnostic group by time by hemisphere by region by Brodmann’s area interaction.
Uncorrected p values are followed by Huynh-Feldt corrected p in parentheses. Interactions at trend level of significance (p<0.10) are in italics. Note that parietal areas 1, 2, 3, and 5 were combined in these analyses, hence 1/2/3/5.
