A survey of the availability in Canadian pharmacy chains of over-the-counter natural health products for menopause symptoms.
Article in BMC complementary and alternative medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
backgroundMenopause is a natural phase in a woman's aging process, characterized by the cessation of menstruation. Women who are going through the menopause transition can experience physiological symptoms that significantly impact their quality of life. Concern about adverse effects of traditional hormone therapy often leads women to purchase over-the-counter (OTC) natural health products (NHPs). The goal of this study was toinvestigate the range of OTC NHPs for menopause available to Canadian women, and the packaging information they can access to make self-management decisions.
methodsEdmonton stores belonging to each of nine Canadian pharmacy chains were visited to identify NHPs marketed for the relief of menopausal symptoms. Details were extracted from the packaging: a) product name and manufacturer, b) Health Canada license number, c) medically active ingredients, d) claims of efficacy, e) contra-indications and warnings, and f) daily cost. Data were entered and analyzed using Microsoft Excel.
resultsWe identified 20 OTC NHP menopausal products, 19 of which had Health Canada license numbers. Twenty-eight medically active ingredients were identified, with the most common being black cohosh (in 14 products) and soy isoflavones (n = 7), chaste tree (n = 5), and dong quai (n = 3). Most products claimed they would relieve vasomotor symptoms, including hot flashes (n = 14) and night sweats (n = 10). Each product had a labeled contraindication for at least one specific condition. Costs per recommended daily dose ranged from $0.07 to a maximum of $2.50 (CAD$).
conclusionNatural health products for menopausal symptoms are easily available to Canadian women. The lack of clear evidence of product efficacy makes the need for easily accessible, balanced information on this topic important for women to make well informed choices.
