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 cardiac beta-adrenergic pathway potently stimulates myocardial performance, thereby providing a mechanism for myocardial contractile reserve. beta-Adrenergic activation also increases cardiac nitric oxide (NO) production, which attenuates positive inotropy, suggesting a possible negative feedback mechanism. Recently, in vitro studies suggest that stimulation of the beta(3)-adrenoceptor results in a negative inotropic effect through NO signaling. In this study, using mice with homozygous beta(3)-adrenoceptor deletion mutations, we tested the hypothesis that the beta(3)-adrenoceptor is responsible for beta-adrenergic activation of NO. Although resting indices of myocardial contraction were similar, beta-adrenergic-stimulated inotropy was increased in beta(3)(-/-) mice, and similar hyper-responsiveness was seen in mice lacking endothelial NO synthase (NOS3). NOS inhibition augmented isoproterenol-stimulated inotropy in wild-type (WT), but not in beta(3)(-/-) mice. Moreover, isoproterenol increased myocardial cGMP in WT, but not beta(3)(-/-), mice. NOS3 protein abundance was not changed in beta(3)(-/-) mice, and cardiac beta(3)-adrenoceptor mRNA was detected in both NOS3(-/-) and WT mice. These findings indicate that the beta(3)-adrenergic subtype participates in NO-mediated negative feedback over beta-adrenergic stimulation.
