Pre-diagnostic plasma endogenous steroids and the risk of exfoliation glaucoma.
Article in medRxiv : the preprint server for health sciences, 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
Purpose: Exfoliation glaucoma (XFG) is the most common secondary glaucoma. Prior studies suggest a higher incidence in women and links to reproductive history, implying estrogen-related pathways. Metabolomic data also indicated inverse associations with steroid-related plasma metabolites, suggesting steroid involvement in XFG pathogenesis. Methods: We conducted a nested case-control study within the Nurses' Health Study (NHS) (1980-2018), NHSII (1989-2019), and Health Professionals Follow-up Study (1986-2018), with 217 XFG suspect (XFGS)/XFG cases and 217 matched controls (62 men and 372 women). We evaluated 18 endogenous steroids and five steroid classes using conditional logistic regression. Secondary analyses examined effect modifications by age and residential latitude, and heterogeneity by disease severity (XFGS vs. XFG). Metabolite set enrichment analysis (MSEA) was used for class-level associations. Multiple comparisons were addressed using the number of effective tests (NEF) for individual steroids and false discovery rate (FDR) for steroid classes. Results: No individual steroid or steroid class met NEF- or FDR-adjusted significance thresholds, overall or by sex. Nonetheless, across both sexes, MSEA demonstrated a non-significant inverse trend between androgen levels and XFG/XFGS risk (FDR=0.22), with 11-ketotestosterone showing a nominal inverse association (OR=0.54; 95%CI=0.31-0.93; P=0.03). Progestogens showed enrichment scores in the positive trend (FDR=0.31), with a borderline positive association between progesterone and XFG/XFGS (OR=2.21; 95%CI=1.00-4.87; P=0.05). Conclusions: Although we observed no statistically significant associations with steroids after correction for multiple testing, the suggestive patterns for androgens and progestogens support the possibility of steroid-related pathways in XFG etiology and support further evaluation in larger studies.
