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

objectiveAldosterone (Aldo) antagonism prevents cardiovascular mortality by unclear mechanisms. Aldo binds to the mineralocorticoid receptor (MR), a ligand-activated transcription factor, which is expressed in human vascular cells. Here we define the early Aldo-regulated vascular transcriptome and investigate the mechanisms of gene regulation by Aldo in the vasculature that may contribute to vascular disease. METHODS AND

resultsGene expression profiling of Aldo-treated mouse aortas identified 72 genes regulated by Aldo. These genes are overrepresented in Gene Ontology categories involved in vascular function and disease. Quantitative reverse transcription-polymerase chain reaction was used to confirm and further explore mechanisms of vascular gene regulation by Aldo. Aldo-regulated vascular gene expression was inhibited by actinomycin D and MR antagonists supporting a transcriptional MR-dependent mechanism. Aldo regulation of a subset of genes was enhanced in the setting of vascular endothelial denudation and blocked by the free radical scavenger Tempol, supporting synergy between Aldo and vascular injury that is oxidative stress dependent. In the aortic arch, a region predisposed to atherosclerosis, the injury-enhanced genes also demonstrated enhanced expression compared with the descending aorta, both at baseline and after Aldo exposure. Furthermore, the clinically beneficial MR antagonist spironolactone inhibited expression of the identified genes in aortic tissue from humans with atherosclerosis.

conclusionsThis study defines the Aldo-regulated vascular transcriptome and characterizes a subset of proatherogenic genes with enhanced Aldo-stimulated, oxidative stress-dependent expression in the setting of vascular injury and in areas predisposed to atherosclerosis. Inhibition of MR regulation of these genes may play a role in the protective effects of Aldo antagonists in patients with vascular disease, and these pathways may provide novel drug targets to prevent atherosclerosis in humans.
