Effects of Flaxseed on Perimenopausal Symptoms: Findings From a Single-Blind, Randomized, Placebo-Controlled Study.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Background Flaxseed contains many phytoestrogens that share structural similarities with endogenous estrogens. It has beneficial properties that improve hormonal effects that may influence chronic disorders. Objective This study aims to evaluate the impact of flaxseed supplementation on perimenopausal syndrome symptoms and serum polyphenol metabolites enterodiol (ED) and enterolactone (EL). Methods Recruitment of 145 perimenopausal women from Queen Mary's Hospital OPD in K.G.M.U. Lucknow, India, was done for this single-blind randomized placebo-controlled experiment, considering inclusion and exclusion criteria. We randomly divided subjects into two groups using a computer-generated random number table. The intervention group A received 10 grams of flaxseed powder, while the placebo group B received 10 grams of roasted wheat flour for a continuous three months. We measured their demographic characteristics, menopausal symptoms score using the modified Kupperman's index (KI), the menopause rating scale (MRS), and the menopause-specific quality of life (MENQOL) intervention questionnaire. Moreover, using high-performance liquid chromatography (HPLC), biochemical parameters (ED, EL) were assessed both at baseline and after three months. For the statistical analysis, Statistical Product and Service Solutions (SPSS, version 24; IBM SPSS Statistics for Windows, Armonk, NY) was employed. Result The study involved 123 individuals, with 22 subjects losing out during follow-up. From baseline to follow-up comparison, the intervention group demonstrated an average percentage decline in the final score of the KI, MRS, and MENQOL intervention questionnaire of -47.25%, -54.05%, and -50.39%, respectively, while the placebo group demonstrated an average percentage decline of -3.83%, -4.91%, and -7.92%, respectively. From baseline to follow-up, ED and EL levels increased by 2.81-fold and 8.55-fold in the intervention group and decreased by 0.25-fold and 0.27-fold in the placebo group. Conclusion Following three months of supplementation, the intervention group showed substantially lower menopausal symptoms (p < 0.001), and ED and EL levels were considerably higher (p < 0.001). Therefore, flaxseed might ameliorate the symptoms associated with perimenopause.
