Table 1.

ANOVA and Bonferroni corrected post-hoc t-test results summary for significant cognitive outcomes. Table summarises the day (D) and day × treatment (D*T) interaction effects from the chronic ANOVAs (effects compared across treatments at pre-dose on Day 28) and repetition (R) and repetition × treatment (R*T) interaction effects from the acute ANOVAs (effects within Day 1 and Day 28) as well as the Bonferroni corrected post-hoc t-tests and effect sizes from the latter for the three significant cognitive outcomes. Here, G = Ginkgo biloba and P = placebo versus (V) the Sideritis scardica (475 mg and 950 mg) treatments.
