Association of dietary isoflavones intake with all-cause mortality and heart disease mortality: a prospective cohort study.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveIsoflavones, a group of soybean nutrients, have been found to provide a wide range of benefits to the human body. The prospective cohort study aims to examine the association of dietary intake of isoflavones with all-cause mortality and heart disease mortality in the US. MATERIALS AND
methodsIn this study, We conducted to explore the potential correlation of isoflavones (total isoflavones, genistein, and daidzein) intake with the risk of all-cause mortality and heart disease mortality. The mortality status and the heart disease cause of death were determined by NHANES-linked National Death Index public access files through December 31, 2019. The association of dietary isoflavones intake with all-cause mortality and heart disease mortality was analyzed by multivariate Cox regression model to compute hazard ratio (HR) and 95% confidence interval (CI), with adjustment for some demographic characteristics, lifestyle factors, and comorbidities. In addition, we employed Kaplan-Meier curves, subgroups and restricted cubic spline models to assess the effect of dietary isoflavones in different circumstances.
resultThe final study population was 11,979 participants, with 1423 participants determined as deceased (7.95%). After adjusting for multiple variables, the study identified an inverse relationship between total isoflavones [Hazard Ratio (HR) 0.85, 95% CI: 0.74-0.99], genistein [HR 0.82, 95% CI: 0.69-0.98], daidzein [HR 0.81, 95% CI: 0.70-0.94] and the incidence of all-cause mortality. Similarly, only high levels of intake daidzein [HR 0.73, 95% CI: 0.53-0.99] were no significantly associated with heart disease mortality. Additionally, a non-linear relationship was observed between dietary isoflavones and all-cause mortality in female participants (p-value for nonlinear < 0.05 and p-value for overall < 0.05).
conclusionOur findings suggest dietary intake of total isoflavones, genistein, and daidzein in the right amounts was associated with lower all-cause mortality and exhibited an association of results for mortality from heart disease with daidzein to diminish the chances of heart disease mortality. The present study reveals a U-shaped association between dietary isoflavones and all-cause mortality in female participants.
