Astrocytic and microglial response in experimentally induced diabetic rat brain.
Article in Metabolic brain disease, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 51 papers, 1 of them a synthesis that pooled 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.
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
Diabetes Mellitus is associated with increased risk of cognitive and behavioural disorders with hitherto undeciphered role of glia. Glia as majority population in brain serve several vital functions, thus require pertinent revelation to further explicate the mechanisms affecting the brain function following diabetes. In this study we have evaluated glial changes in terms of phenotypic switching, proliferation and expression of activation cell surface markers and associated cellular degeneration in hippocampus following STZ-induced diabetes and caused cognitive impairments. Experimental diabetes was induced in Wistar rats by a single dose of STZ (45 mg/kg body weight; intraperitoneally) and changes were studied in 2nd, 4th and 6th week post diabetes confirmation using Barnes maze and T-maze test, immunohistochemistry and image analysis. An increase in GFAP expression sequentially from 2nd to 6th weeks of diabetes was analogous with the phenotypic changes and increased astrocyte number. Elevated level of S100β with defined stellate morphology further confirmed the astrocytosis following diabetes. Enhanced level of Iba-1 and MHC-II revealed the corroborated microglial activation and proliferation following diabetes, which was unresolved till date. Increased caspase-3 activity induced profound cell death upto 6th weeks post diabetes confirmation. Such caspase 3 mediated cellular damage with a concomitant activation of the astrocytes and microglia suggests that diabetes linked cell death activates the astrocytes and microglia in hippocampus which further underpin the progression and severity of brain disorders resulting in cognitive and behavioural impairments.
