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
Introduction: There is no comparison of iron phenotypes and menses, pregnancies, and live births reports of women with Subjects and Methods: We compared phenotypes and reports of non-Hispanic white women women aged ≥25 y in post-population screening evaluations using univariable methods. Results: There were 153 p.C282Y/p.C282Y and 273 wt/wt. Median ages were 50 y (25, 86) and 55 y (25, 92), respectively (p=0.0019). Median transferrin saturation (TS), median serum ferritin (SF), and provisional iron overload prevalence were higher in p.C282Y/p.C282Y (p ≤0.0001, each comparison). Prevalences of documented iron overload (3.3% p.C282Y/p.C282Y vs. 0.7% wt/wt), iron overload-related disease (2.0% vs. 0.4%, respectively), and iron deficiency (3.9% vs. 2.6%, respectively) were not significantly different. Median ages at menarche (13 y p.C282Y/p.C282Y vs. 13 y wt/wt) and menopause (50 y vs. 49 y, respectively) were not significantly different. Reports of "in-between bleeding?" (24.2% p.C282Y/p.C282Y vs. 25.2% wt/wt, respectively), "early stopping of periods?" (11.8% vs. 13.9%, respectively), and "had a hysterectomy?" (30.1% vs. 35.9%, respectively) were not significantly different. Respective percentage pairs of women with p.C282Y/p.C282Y and wt/wt who reported 0, 1, 2, 3, or ≥4 pregnancies (or live births) did not differ significantly. Live births/pregnancies were 287/363 (79.1%, p.C282Y/p.C282Y) and 534/673 (79.3%, wt/wt) (p=0.7549). Conclusions: Median TS, median SF, and provisional iron overload prevalence are greater in women with
