Decrease in Adult Neurogenesis and Neuroinflammation Are Involved in Spatial Memory Impairment in the Streptozotocin-Induced Model of Sporadic Alzheimer's Disease in Rats.
Article in Molecular neurobiology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 43 papers.
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.
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
Early impairments in cerebral glucose metabolism and insulin signaling pathways may participate in the pathogenesis of the sporadic form of Alzheimer's disease (sAD). Intracerebroventricular (ICV) injections of low doses of streptozotocin (STZ) are used to mimic sAD and study these alterations in rodents. Streptozotocin causes impairments in insulin signaling and has been reported to trigger several alterations in the brain, such as oxidative stress, neuroinflammation, and dysfunctions in adult neurogenesis, which may be involved in cognitive decline and are features of human AD. The aim of the present study was to assess the influence of neuroinflammation on the process of adult neurogenesis and consequent cognitive deficits in the STZ-ICV model of sAD in Wistar rats. Streptozotocin caused an acute and persistent neuroinflammatory response, reflected by reactive microgliosis and astrogliosis in periventricular areas and the dorsal hippocampus, accompanied by a marked reduction of the proliferation of neural stem cells in the dentate gyrus of the hippocampus and subventricular zone. Streptozotocin also reduced the survival, differentiation, and maturation of newborn neurons, resulting in impairments in short-term and long-term spatial memory. These results support the hypothesis that neuroinflammation has a detrimental effect on neurogenesis, and both neuroinflammation and impairments in neurogenesis contribute to cognitive deficits in the STZ-ICV model of sAD.
