Endogenous Estrogen Exposure and All-Cause Mortality Among Women with Overweight or Obesity According to Metabolic Health Status: Insights from an 18-Year Prospective Cohort Study.
Article in International journal of women's health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Despite extensive research on estrogen and its implications, there remains a gap in understanding the relationship between the duration of endogenous estrogen exposure (EEE) and all-cause mortality among women with overweight or obesity according to their metabolic health status. Therefore, this study examined the association between EEE duration and all-cause mortality over an 18-year follow-up period, separately among women with metabolically healthy overweight/obesity (MHO) and those with metabolically unhealthy overweight/obesity (MUO). Methods: In this large population-based cohort, 1162 post-menarcheal women aged ≥20 years with a body mass index (BMI) ≥25 kg/m Results: During the follow-up, 62 deaths occurred (2.2 per 1000 person-years; 95% CI: 1.7-2.8), including 20 in the MHO group and 42 in the MUO group. Among individuals with MHO, incidence rates per 1000 person-years (95% CI) were 0.94 (0.42-2.11), 1.50 (0.81-2.79), and 0.60 (0.22-1.60) across the first, second, and third EEE tertiles, respectively. Corresponding rates for MUO were 6.46 (4.02-10.40), 3.42 (1.78-6.58), and 6.05 (3.71-9.88). After adjusting for confounders, the highest EEE tertile in MHO was associated with a significantly lower hazard of all-cause mortality (HR: 0.19; 95% CI: 0.05-0.76). Conclusion: Longer EEE durations appear to reduce the risk of all-cause mortality among women with overweight/obesity who are metabolically healthy.
