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

Reperfusion therapy after cerebral ischemia often leads to reperfusion injury which may cause brain edema and blood-brain barrier (BBB) dysfunction. As a natural bioflavonoid, quercetin may exert protective effects on BBB dysfunction. This study aimed to investigate effects of quercetin in a rat model of global cerebral ischemia reperfusion (I/R) injury and explore the potential mechanism. Male rats were randomly divided into 4 groups: sham group, I/R group, quercetin-treated group (25 μmol/kg twice daily for 3 consecutive days before I/R), and quercetin/DKK-1-treated group. Global cerebral I/R was induced by bilateral common carotid artery occlusion combined with hypotension for 20 min and reperfusion for 24 h. Neurological function was scored, and then rats were sacrificed. The brain was harvested for HE staining, NeuN staining, and detection of brain water content. The BBB structure and permeability were examined by transmission electron microscopy and Evans blue extravasation, respectively. The protein expression of MMP-9, ZO-1, Claudin-5, β-catenin, and GSK-3β, and the mRNA expression of Axin and LEF1 were detected in either the absence or presence of Wnt/β-catenin inhibitor DKK-1. Results showed that quercetin reduced brain edema and BBB leakage, and improved BBB dysfunction. Quercetin could increase the expression of ZO-1, Claudin-5, β-catenin, and LEF1, and decrease the expression of MMP-9, GSK-3β and Axin. And all these protective effects of quercetin could be reversed by DKK-1. Thus, quercetin can alleviate BBB dysfunction after global cerebral I/R in rats and the mechanism may be related to the activation of canonical Wnt/β-catenin signaling pathway.
