at the margin of significancep= 0.053
On the specific drug vs placebo comparison at week 12, the preferential improvement for drug in overall cognition fell at the margin of significance (p= 0.053); because this fell at the margin of significance and because the sample size was small, this result must be viewed with caution, and requires replication for confirmation of a treatment effect, as there is a slightly increased risk that this result occurred by chance.
