Means and SD. Significant p values are shown in bold.
Global cognitive index and cognitive domain scores are z-transformed values. Z-score transformation is based on control group mean and variance at baseline.
a
ANOVA (all groups, with significant Sidak post hoc test vs control group: *p<0.05; **p<0.01; ***p<0.001).
