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

rationaleAngiotensin II (Ang II) has diverse effects on smooth muscle cells (SMCs). The diversity of effects may relate to the regional location of this cell type.

objectiveThe aim of this study was to define whether Ang II exerted divergent effects on smooth muscle cells in the aorta and determine the role of blood pressure and specific oxidant mechanisms. METHODS AND

resultsAng II (1000 ng/kg per minute) infusion for 28 days into mice increased systolic blood pressure and promoted medial expansion of equivalent magnitude throughout the entire aorta. Both effects were ablated by angiotensin II type 1a (AT(1a)) receptor deficiency. Similar increases in systolic blood pressure by administration of norepinephrine promoted no changes in aortic medial thickness. Increased medial thickness was attributable to SMC expansion owing to hypertrophy in most aortic regions, with the exception of hyperplasia of the ascending aorta. Deficiency of the p47(phox) component of NADPH oxidase ablated Ang II-induced medial expansion in all aortic regions. Analysis of mRNA and protein throughout the aorta revealed a much higher abundance of the inhibitor of differentiation 3 (Id3) in the ascending aorta compared to all other regions. A functional role was demonstrated by Id3 deficiency inhibiting Ang II-induced SMC hyperplasia of the ascending aorta.

conclusionsIn conclusion, Ang II promotes both aortic medial hypertrophy and hyperplasia in a region-specific manner via an oxidant mechanism. The ascending aortic hyperplasia is dependent on Id3.
