NOTES

Pairwise statistical differences between groups

differs from controls, p<.05

^**

differs from controls, p<.01

⁺

differs from PD, p<.05

⁺⁺

differs from PD, p<.012.

For all statistically significant comparisons of DLB/PDD patients to Controls, the effect size is “large” (Cohen's d > .8).
