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

Stroke triggers a systemic inflammatory response that exacerbates the initial injury. Immunizing with peptides derived from CNS proteins can stimulate protective autoimmunity (PA). The most renowned of these peptides is copolymer-1 (Cop-1) also known as glatiramer acetate. This peptide has been approved for use in the treatment of multiple sclerosis. Cop-1-specific T cells cross the blood-brain barrier and secrete neurotrophins and anti-inflammatory cytokines that could stimulate proliferation of neural precursor cells and recruit them to the injury site; making it an ideal therapy for acute ischemic stroke. The aim of this work was to evaluate the effect of Cop-1 on neurogenesis and neurological recovery during the acute phase (7 days) and the chronic phase of stroke (60 days) in a rat model of transient middle cerebral artery occlusion (tMCAo). BDNF and NT-3 were quantified and infarct volumes were measured. We demonstrated that Cop-1 improves neurological deficit, enhances neurogenesis (at 7 and 60 days) in the SVZ, SGZ, and cerebral cortex through an increase in NT-3 production. It also decreased infarct volume even at the chronic phase of tMCAo. The present manuscript fortifies the support for the use of Cop-1 in acute ischemic stroke.
