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

objectivesGrowing evidence indicates that extract of Ginkgo biloba (EGb) attenuates hippocampal-dependent memory deficit in aged individuals; however, very little is known about the effect of EGb on the structure of hippocampus. Therefore we examined the EGb-induced morphological changes of the Cornu Ammonis (CA) region in aged rats. MATERIALS AND

methodsSixteen aged male Wistar rats, 24 months old, were randomly divided into experimental and control groups. Experimental group was orally administered EGb (100 mg/kg/d for 8 weeks), and the control group received a similar volume of water. The volume estimation of CA hippocampal field was done by Cavalieri principle and a quantitative Golgi study was also used for analysis of dendritic arborizations of CA3 and CA1 pyramidal cells.

resultsResults revealed that EGb-treated aged rats had greater volumes than control animals in the layers of pyramidal and radiatum lacunosum moleculare in both CA3 and CA1 subfields. The neurons of CA3 and CA1 in experimental rats had more dendritic segments and larger total dendritic length compared to the control. The results also showed that the aged rats treated by EGb had more numerical branching density in the apical dendrites of CA3 and CA1 pyramidal cells.

conclusionThe results of the present study show that long-term administration of EGb could produce morphometrical changes in hippocampal pyramidal cells in aged rats. Results also provide a neuroanatomical basis for memory improvement due to chronic treatment with EGb.
