Steroid hormone metabolites and mammographic breast density in premenopausal women.
Article in British journal of cancer, 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
backgroundSteroid hormones influence breast morphology and cellular proliferation and are associated with breast carcinogenesis. However, their associations with mammographic breast density (MBD) are less studied, particularly in premenopausal women. We, therefore, investigated the associations of steroid hormone metabolites with MBD in premenopausal women.
methodsOur study included 700 premenopausal women scheduled for screening mammograms. We analyzed 54 steroid hormone metabolites (Metabolon®) and assessed volumetric measures of MBD including volumetric percent density (VPD), dense volume (DV), and non-dense volume (NDV) using Volpara. We investigated associations using linear regression modeling to estimate the covariate-adjusted means of VPD, NDV, and DV, corresponding to each steroid hormone metabolite tertile and on a continuous scale. Models were adjusted for age, body fat percentage, age at menarche, race, alcohol consumption, family history of breast cancer, oral contraceptive use, body shape at age 10, and parity/age at first birth. We applied false discovery rate (FDR) to control multiple testing and determined significance at FDR-adjusted p-value ≤ 0.05.
resultsOne corticosteroid (cortolone glucuronide (1)) and four androgenic steroid metabolites (androstenediol (3beta,17beta) monosulfate (2), androstenediol (3beta,17beta) disulfate (1), 5alpha-androstan-3alpha,17beta-diol monosulfate (2), and 5alpha-androstan-3alpha,17beta-diol disulfate) were inversely associated with VPD. For instance, VPD was lower monotonically across tertiles (T) of cortolone glucuronide (1) (T1 = 8.9%, T2 = 8.3%, and T3 = 7.3%; p-trend=7.55 × 10
conclusionWe identified novel inverse associations of cortolone glucuronide (1) and four androgenic steroid metabolites with VPD, underscoring the importance of steroid hormone metabolites in MBD and the potential for modulating these in reducing MBD.
