Three-dimensional visualization of cerebral blood vessels and neural changes in thick ischemic rat brain slices using tissue clearing.
Article in Scientific reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Blood vessels are three-dimensional (3D) in structure and precisely connected. Conventional histological methods are unsuitable for their analysis because of the destruction of functionally important topological 3D vascular structures. Tissue optical clearing techniques enable extensive volume imaging and data analysis without destroying tissue. This study therefore applied a tissue clearing technique to acquire high-resolution 3D images of rat brain vasculature using light-sheet and confocal microscopies. Rats underwent middle cerebral artery occlusion for 45 min followed by 24 h reperfusion with lectin injected directly into the heart for vascular staining. For acquiring 3D images of rat brain vasculature, 3-mm-thick brain slices were reconstructed using tissue clearing and light-sheet microscopy. Subsequently, after 3D rendering, the fitting of blood vessels to a filament model was used for analysis. The results revealed a significant reduction in vessel diameter and density in the ischemic region compared to those in contralesional non-ischemic regions. Immunostaining of 0.5-mm-thick brain slices revealed considerable neuronal loss and increased astrocyte fluorescence intensity in the ipsilateral region. Thus, these methods can provide more accurate data by broadening the scope of the analyzed regions of interest for examining the 3D cerebrovascular system and neuronal changes occurring in various brain disorders.
