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

Scaffolds composed of extracellular matrix (ECM) are being investigated for their ability to facilitate brain tissue remodeling and repair following injury. The present study tested the hypothesis that the implantation of brain-derived ECM would attenuate experimental traumatic brain injury (TBI) and explored potential underlying mechanisms. TBI was induced in mice by a controlled cortical impact (CCI). ECM was isolated from normal porcine brain tissue by decellularization methods, prepared as a hydrogel, and injected into the ipsilesional corpus callosum and striatum 1 h after CCI. Lesion volume and neurological function were evaluated up to 35 d after TBI. Immunohistochemistry was performed to assess post-TBI white matter integrity, reactive astrogliosis, and microglial activation. We found that ECM treatment reduced lesion volume and improved neurobehavioral function. ECM-treated mice showed less post-TBI neurodegeneration in the hippocampus and less white matter injury than control, vehicle-treated mice. Furthermore, ECM ameliorated TBI-induced gliosis and microglial pro-inflammatory responses, thereby providing a favorable microenvironment for tissue repair. Our study indicates that brain ECM hydrogel implantation improved the brain microenvironment that facilitates post-TBI tissue recovery. Brain ECM offers excellent biocompatibility and holds potential as a therapeutic agent for TBI, alone or in combination with other treatments.
