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

There is substantial evidence that there are dramatic sex-related differences in the incidence of cardiovascular disease, apparently related to the presence of steroid hormones. This is supported by the discovery of steroid hormone receptors in the heart and vasculature. More controversial is the area of sex-related differences in cardiac metabolism and function. A number of human and animal studies have demonstrated that estrogen and testosterone have cardiac metabolic effects. Additionally, research shows females have higher heart rates and various indices of function, including cardiac output and stroke volume, compared with males. However, some controversy exists, as other studies report that function in isolated muscle preparations is lower in females versus males. The reasons for these differences may reflect effects of sex hormones that are dependent on the conditions being studied. Cardiac function is reduced in postmenopausal females, suggesting that female sex hormones, specifically estrogen and progesterone, influence cardiac function. Apart from its well-documented vasodilatory effects, estrogen has also been shown to have negative inotropic effects and to reduce Ca(2+) transients in cardiomyocytes. Similar results have been found for progesterone. Several studies show that testosterone administration appears to increase cardiac performance, while others show that it increases the stiffness of the ventricle due to increased collagen synthesis, thereby reducing diastolic performance. This review will discuss current evidence suggesting sex-related differences in cardiac metabolism and its energetics and function and will present the potential role of the principal sex steroid hormones.
