Improved assessment of outcomes following transient global cerebral ischemia in mice.
Article in Experimental brain research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Mouse models of global cerebral ischemia (GCI) allow experimental examination of cerebral pathophysiology in genetically modified mice and fast screening of new treatment strategies. Various surgical protocols of GCI-induction in mice have been published; however, many of these studies are hindered by limited neurological assessment protocols and present insufficient reporting of the cumulative survival rate. Therefore, we aim at developing a reproducible and easily implementable model of transient GCI in mice with minimal impact on normal mouse behavior. GCI was induced in male C57BL/6 mice by bilateral occlusion of the common carotid arteries for 10 min combined with isoflurane-induced hypotension which resulted in severe reduction in the cerebral blood flow of the forebrain. Sham operation served as a control. Exploratory behavior was evaluated in a home-cage environment the day before and again daily for up to 7 days after GCI or sham operation and was found to be significantly decreased 1-7 days after GCI compared to sham. Furthermore, we found delayed neuronal cell death in the frontal cortex and hippocampus 5 and 7 days after GCI but not at day 3 or after sham operation. The survival rate at day 7 was 100 % after sham operation and 42 % after GCI. The model of GCI in mice presented in this study compromises the exploratory behavior and resembles the cerebral damage and mortality rate seen after cardiac arrest and/or GCI in man, and is therefore a good model to use for studies of GCI pathophysiology.
