In vivo neuroprotection in ischemic stroke by activated protein C requires β-arrestin 2.

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
The protease activated protein C (APC) and its variants provide neuroprotection for murine ischemic stroke and mortality reduction for murine sepsis. For these actions, APC's in vivo mechanism of action, similar to in vitro studies using cultured cells, involves protease activated receptor 1 (PAR1)-mediated biased signaling. APC/PAR1 signaling in vitro requires β-arrestin 2, an intracellular scaffold protein, and β-arrestin 2-initiated signaling can alter diverse intracellular signaling pathways. This study used a proximal transient middle cerebral artery occlusion model to study the neuroprotective actions of the signaling-selective APC variant, 3K3A-APC, in β-arrestin 2-deficient (
