Characteristics of included studies and participants, Ginkgo biloba for dementia
The 12-26 weeks outcomes of the studies for the whole patient group together (Alzheimer's disease, vascular dementia or mixed dementia) are presented in the next section. We present the results within different outcome domains. Furthermore, results are compared with the 52-weeks outcomes of the only long-term study [30]. Within the respective sections, we present data from the subgroup of patients with Alzheimer's disease. Analyses of other subgroups are reported separately. For all outcomes, negative change scores indicate an improvement.
