The repeated measures ANOVA revealed an absence of any significant group differences (HC, CHR, YSZ) in the total power GBR (Figure 1a, 2a). Furthermore, the Site and Group X Site interaction effects were not significant. A priori pairwise comparisons showed that age-corrected total power GBR factor z-scores were marginally reduced in YSZ relative to HC (Cohen’s d=.43; p=0.072). No reduction in total power GBR was observed in the CHR group relative to the HC group (Cohen’s d=.09; p=.687).
