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

purpose of reviewWe review our approach of using MSNA-coupled fMRI to identify how different regions of the brain interact to control blood pressure. By performing functional magnetic resonance imaging (fMRI) of the brain at the same time as recording muscle sympathetic nerve activity (MSNA), via a microelectrode in the common peroneal nerve, we can identify areas of the brain involved in the generation of sympathetic outflow to the muscle vascular bed, a major contributor to blood pressure regulation. RECENT

findingsTogether with functional connectivity analysis of areas identified through MSNA-coupled fMRI, we have established key components of the human sympathetic connectome and their roles in the control of blood pressure. Whilst our studies confirm the roles of nucleus tractus solitarius (NTS), caudal ventrolateral medulla (CVLM) and rostral ventrolateral medulla (RVLM) in the baroreflex-mediated control of MSNA, we have identified cortical areas - dorsolateral prefrontal cortex, precuneus and insula - that are coupled to RVLM via the hypothalamus and midbrain periaqueductal gray (PAG). This emphasizes the roles of areas above the brainstem in the regulation of blood pressure.
