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

Despite ischemic stroke being the fifth leading cause of death in the USA, there are few therapeutic options available. We recently showed that the neuroprotective compound P7C3-A20 reduced brain atrophy, increased neurogenesis, and improved functional recovery when treatment was initiated immediately post-reperfusion after a 90-min middle cerebral artery occlusion (MCAO). In the present study, we investigated a more clinically relevant therapeutic window for P7C3-A20 treatment after ischemic stroke. MCAO rats were administered P7C3-A20 for 1 week, beginning immediately or at a delayed point, 6 h post-reperfusion. Delayed P7C3-A20 treatment significantly improved stroke-induced sensorimotor deficits in motor coordination and symmetry, as well as cognitive deficits in hippocampal-dependent spatial learning, memory retention, and working memory. In the cerebral cortex, delayed P7C3-A20 treatment significantly increased tissue sparing 7 weeks after stroke and reduced hemispheric infarct volumes 48 h after reperfusion. Despite no reduction in striatal infarct volumes acutely, there was a significant increase in spared tissue volume chronically. In the hippocampus, only immediately treated P7C3-A20 animals had a significant increase in tissue sparing compared to vehicle-treated stroke animals. This structural protection translated into minimal hippocampal-dependent behavioral improvements with delayed P7C3-A20 treatment. However, all rats treated with delayed P7C3-A20 demonstrated a significant improvement in both sensorimotor tasks compared to vehicle controls, suggesting a somatosensory-driven recovery. These results demonstrate that P7C3-A20 improves chronic functional and histopathological outcomes after ischemic stroke with an extended therapeutic window.
