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

The von Willebrand factor (vWF) is a plasma glycoprotein that plays an essential role in hemostasis by supporting platelet adhesion and thrombus formation in response to vascular injury. Plasma levels of vWF are an independent risk factor for patients with acute myocardial infarction (AMI); however, clinical data have demonstrated a marked variation of vWF levels in patients with AMI, the reason for which has not yet been identified. In the present study, a rat model of ST-segment elevation AMI was established, and cardiac and peripheral blood was collected for a time-course examination of the plasma levels of vWF and tumor necrosis factor-α (TNF-α). The level of vWF in the blood plasma increased, peaked at 1 h and decreased to normal levels by day 7 following AMI, while the level of TNF-α peaked at 24 h and remained elevated until day 7. The effects of TNF-α on vWF secretion and expression were examined in cultured human umbilical vascular endothelial cells (HUVECs). TNF-α treatment increased vWF secretion from the HUVECs but inhibited the mRNA and protein expression of vWF in the HUVECs. These results indicate that vWF secretion from endothelial cells is transiently elevated following AMI, and then decreases as the expression of vWF is inhibited by TNF-α. The present study increases the understanding of the pathophysiology of vWF and indicates that the determination of vWF levels may be useful in the clinical evaluation of AMI.
