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

objectiveAortic wave reflection characteristics, such as augmentation index, are positively related to muscle sympathetic nerve activity in young men. In young women, there is an inverse relationship. We investigated whether this inverse relationship persisted in postmenopausal women.

methodsMuscle sympathetic nerve activity (peroneal microneurography) and arterial pressure (brachial catheter) were measured in 16 postmenopausal women (mean [SEM] age, 60 [2] y). Aortic blood pressure and wave form characteristics were synthesized from radial arterial pressure waves (applanation tonometry). Specifically, augmentation index, wave reflection amplitude, and estimated wasted left ventricular energy were calculated. These data were compared with our previously published work from an identical protocol in 23 young women (mean [SEM] age, 25 [1] y).

resultsTonic sympathetic activity was higher in postmenopausal women than in young women (64 [3] vs 24 [4] bursts/100 heartbeats). All indices of aortic wave reflection were higher in postmenopausal women than in young women (P < 0.05). Baseline sympathetic activity was inversely related to augmentation index (r = -0.63, P < 0.05), augmented pressure (r = -0.62, P < 0.05), and wasted left ventricular energy (r = -0.61, P < 0.05) in young women. Conversely, baseline sympathetic activity was positively related to augmentation index (r = 0.63, P = 0.09), augmented pressure (r = 0.69, P < 0.05), and wasted left ventricular energy (r = 0.79, P < 0.05) in postmenopausal women.

conclusionsHigh levels of sympathetic activity are associated with higher indices of aortic wave reflection in postmenopausal women. Consequently, postmenopausal women with high sympathetic activity may be more at risk for developing cardiovascular diseases or experiencing adverse cardiovascular system-related events.
