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

Intracerebral hemorrhage (ICH) represents the deadliest subtype of all strokes. The development of brain edema, a consequence of blood-brain barrier (BBB) disruption, is the most life-threatening event after ICH. Pathophysiological conditions activate the endothelium, one of the components of BBB, inducing rearrangement of the actin cytoskeleton. Upon activation, globular actin assembles into a filamentous actin resulting in the formation of contractile actin bundles, stress fibers. The contraction of stress fibers leads to the formation of intercellular gaps between endothelial cells increasing the permeability of BBB. In the present study, we investigated the effect of ICH on stress fiber formation in CD1 mice. We hypothesized that ICH-induced formation of stress fiber is triggered by the activation of PDGFR-β and mediated by the cortactin/RhoA/LIMK pathway. We demonstrated that ICH induces formation of stress fibers. Furthermore, we demonstrated that the inhibition of PDGFR-β and its downstream reduced the number of stress fibers, preserving BBB and resulting in the amelioration of brain edema and improvement of neurological functions in mice after ICH.
