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

Vascular calcification predicts an increased risk for cardiovascular events in atherosclerosis, diabetes, and end-stage kidney diseases. Matrix Gla protein (MGP), an inhibitor of calcification, limits calcium phosphate deposition in the vessel wall. There are many factors contributing to the progression of atherosclerosis, including hypertension, hyperlipidemia, the renin-angiotensin system, and inflammation. Angiotensin II (ANG II) plays a crucial role in the atherogenic process through not only its pressor responses but also its growth-promoting and inflammatory effects. In this study, we investigated the role of MGP in ANG II-induced exacerbation of vascular calcification in human vascular smooth muscle cells (VSMCs). The expression of MGP, calcification, and apoptosis in human VSMCs were examined by Western blot analysis, real-time PCR, in situ terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling, and enzyme-linked immunosorbent assay, respectively. Increase in VSMC calcification in human atherosclerotic plaques upregulates MGP expression and apoptosis in a negative feedback manner. ANG II inhibited MGP expression in VSMCs via and in vitro in a dose- and time-dependent manner through ANG II type 1 receptor and NF-κB signaling pathway. Meanwhile, MGP inhibited the calcification, caspase-3 activity, activation of runt-related transcription factor 2, and release of inflammatory cytokines by VSMCs induced by calcification medium (2.5 mM P(i)) and ANG II in vitro. These observations provide evidence that ANG II exacerbates vascular calcification through activation of the transcription factors, runt-related transcription factor 2 and NF-κB, and regulation of MGP, inflammatory cytokines expression in human VSMCs.
