The Relationship Between Immune Cells and Uterine Fibroids: A Bidirectional Mendelian Randomization 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
Objective: This research applied a bidirectional Mendelian randomization (MR) framework to investigate potential two-way causal associations between immune cell phenotypes and uterine fibroids (UF). Methods: This research drew upon publicly available data from large-scale genome-wide association studies (GWAS), encompassing 731 immune cell phenotypes from 3757 participants and UF data from 21,024 cases and 237,694 controls. Primary causal estimates were derived using the inverse-variance weighted (IVW) approach, with additional validation through MR-Egger, weighted median, and related methods. To ensure the reliability of the results, MR-PRESSO analysis, leave-one-out analysis, and false discovery rate (FDR) correction were also performed. Results: Forward MR analyses initially identified 39 immune phenotypes significantly associated with UF (IVW P < 0.05), comprising 23 risk factors and 16 protective factors. Applying stringent selection criteria-IVW P < 0.001, consistent odds ratio (OR) directions across five analytical methods, and pleiotropy P > 0.05-three phenotypes demonstrated strong causal links with UF: CD39⁺ CD8⁺ T cells, CD25 expression on IgD Conclusion: Our research offers compelling genetic evidence supporting a forward causal link between CD39⁺ CD8⁺ T cells, CD25 on IgD
