Phytoestrogen blood levels and adverse outcomes in women with suspected ischemic heart disease.
Article in European journal of clinical nutrition, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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/
objectivesPrior studies linked higher blood phytoestrogen (phytoE) levels of daidzein to beneficial lipoprotein profiles, and higher genistein levels related to worse coronary microvascular dysfunction in women with suspected ischemic heart disease (IHD). However, relationships to adverse outcomes remain unclear. We investigated the associations between eight serum phytoE and major adverse cardiac events (MACE) including myocardial infarction, stroke, hospitalization for heart failure and angina, cardiovascular and all-cause mortality, in women undergoing functional coronary angiography (FCA) for suspected ischemia. SUBJECTS/
methodsWe evaluated 143 women enrolled in the Women's Ischemia Syndrome Evaluation (1996-2001) for serum phytoE levels and 10-year outcomes. Median follow-up duration was 6.08 years (range 0.01-8.16) for time to MACE and 9.11 years (range 0.01-11.08 years) for time to death. Kaplan-Meier plots were analyzed and Cox regression models adjusted for age, body mass index, hypertension, diabetes, dyslipidemia and tobacco use.
resultsThe median age was 54.7 (range 20.6-76.1) years and BMI was 29.3 (range 18.4-57.2). Of the cohort, 80.4% had nonobstructive coronary artery disease, 56% had hypertension, 22.4% had diabetes, 58.1% had dyslipidemia and 59.4% of the women used tobacco. Each unit decrease in log glycitin was associated with increased MACE hazard (HR 1.97, 95% [CI 1.23, 3.14], p = 0.005). Glycitin absence was associated with earlier angina hospitalization (log rank p = 0.05). After 6 years, MACE increased with each unit decrease in log genistein (HR 6.17, 95% [CI 1.81, 20.8], p = 0.0036). Other phytoE did not show statistically significant associations with outcomes.
conclusionsAmong women with suspected IHD undergoing clinically indicated invasive FCA, low serum glycitin was associated with increased MACE and earlier angina hospitalization, while low genistein was associated with increased MACE after 6 years. Future studies are needed regarding phytoE, nutrition, outcomes and possibly supplementation.
