Forest plot of meta-analysis for EGb 761® 240 mg/die and placebo using random-effect model. Meta-analysis of the data obtained from the systematic literature review was conducted according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analysis [116]. We searched the PubMed, MEDLINE, EMBASE, PsycINFO, CINAHL, Cochrane Database of Systematic Reviews with the terms Ginkgo* or Gingko* or EGB761 or “EGB 761” or EGB-761. For continuous data, standardized mean differences (SMD) was used. Given the expected heterogeneity, we a priori used a random-effects model. Overall, SMD with 95% CI was estimated with DerSimonian–Laird random-effects models. Publication bias was evaluated by a funnel plot and Egger’s linear regression analysis and p < 0.05 was set as the level of significant. This meta-analysis was performed using R 3.6.2.
