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

Brain microvascular endothelium forms an active permeability barrier, the blood-brain barrier (BBB). In neurologic disorders, barrier properties of the BBB are often lost indicating their dependance on molecular cues of the brain microenvironment. In this issue, Osada et al demonstrate that the endothelial extracellular matrix (ECM) provides one of these cues. Their study shows that β1-integrin-mediated adhesion of brain endothelial cells to the surrounding ECM is critical for stabilizing claudin-5 in BBB tight junctions (TJs) and BBB integrity. These observations point to a novel intracellular signaling pathway from β1-integrin/ECM endothelial adhesions to BBB TJs contributing to BBB integrity.
