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

In this review, we highlight that the relationship between muscle sympathetic nerve activity (MSNA) and mean arterial pressure is complex, differs by sex, and changes with age. In young men there is an inverse relationship between MSNA and cardiac output where high MSNA is compensated for by low cardiac output. This inverse relationship is not seen in older men. In young women sympathetic vasoconstriction is offset by β-adrenoreceptor mediated vasodilation, limiting the ability of young women to maintain blood pressure in response to orthostatic stress. However, β-mediated dilation in women is attenuated with age, leading to unopposed α-adrenergic vasoconstriction and a rise in the direct transduction of MSNA into increases in blood pressure. We propose that these changes with age and menopausal status are major contributing factors in the increased prevalence of hypertension in older women. In addition to aging, we highlight that changes in sex hormones in young women (across the menstrual cycle, with oral contraceptive use, or with pregnancy) influence MSNA and the transduction of MSNA into increases in blood pressure. It is likely that the β-adrenergic receptors and/or changes in baroreflex sensitivity play a large role in these sex differences and changes with alterations in sex hormones.
