1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Ginkgo biloba is among the most favourite and best explored herbal drugs. Standardized extracts of Ginkgo biloba represent the only herbal alternative to synthetic antidementia drugs in the therapy of cognitive decline and Alzheimer's diseases. The clinical efficiency of such standardized Ginkgo biloba extracts (GBE) is still controversial, but authors of numerous international clinical studies recommended the use of GBE in the described therapies.Extracts of Ginkgo biloba are a mixture of substances with a wide variety of physical and chemical properties and activities. Numerous pharmacological investigations lead to the conclusion that the terpene trilactones (TTL) and the flavonoids of GBE are responsible for the main pharmacological effects of the extract in the therapy of cognitive decline. Therefore, the quality of GBE products must be oriented on a defined quantity of TTL and flavonoids. Furthermore, because of their toxic potential the amount of ginkgolic acid should be less than 5 ppm.However, data on pharmacokinetics and bioavailability, especially related to the central nervous system (CNS), which is the target tissue, are relatively rare. A few investigations characterize the TTL and flavonoids of Ginkgo biloba pharmacokinetically in plasma and in the brain. Recent investigations show that significant levels of TTL and Ginkgo biloba flavonoids cross the blood-brain barrier and enter the CNS of rats after oral application of GBE. Knowledge about the pharmacokinetic behaviour of these substances is necessary to discuss the pharmacological results on a more realistic basis.
