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

Previous studies have indicated that the generation of newborn hippocampal neurons is impaired in the early phase of Alzheimer's disease (AD). A potential therapeutic strategy being pursued for the treatment of AD is increasing the number of newborn neurons in the adult hippocampus. Recent studies have demonstrated that ginkgo biloba extract (EGb 761) plays a neuroprotective role by preventing memory loss in many neurodegenerative diseases. However, the extent of EGb 761's protective role in the AD process is unclear. In this study, different doses of EGb 761 (0, 10, 20, and 30 mg/kg; intraperitoneal injections once every day for four months) were tested on 5×FAD mice. After consecutive 4-month injections, mice were tested in learning memory tasks, Aβ, and neurogenesis in the dentate gyrus (DG) of hippocampus and morphological characteristics of neurons in DG of hippocampus. Results indicated that EGb 761 (20 and 30 mg/kg) ameliorated memory deficits. Further analysis indicated that EGb 761 can reduce the number of Aβ positive signals in 5×FAD mice, increase the number of newborn neurons, and increase dendritic branching and density of dendritic spines in 5×FAD mice compared to nontreated 5×FAD mice. It was concluded that EGb 761 plays a protective role in the memory deficit of 5×FAD mice.
