Gender differences in the association between marriage and epigenetic age.
Article in Frontiers in aging, 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: Being married is related to better health, but many studies reveal greater health benefits among men relative to women. Some research has indicated that married individuals exhibit decelerated epigenetic age relative to individuals who are not married, but questions remain regarding gender differences therein. The purpose was to investigate gender differences in associations of marital status to epigenetic age (ing) assessed on three clocks/algorithms (PhenoAge, GrimAge, and DunedinPACE). Methods: Data from 762 participants in the national Midlife in the United States Study (MIDUS II; men Results: Being married, relative to being separated or divorced, was associated with decelerated epigenetic aging on DunedinPACE, although not PhenoAge or GrimAge. Investigating gender differences revealed a divergence regarding never marrying, a marital status that accelerated GrimAge and DunedinPACE scores among men, but not women. Discussion: These results contribute new knowledge about marital status and early risk for disease, as indicated by accelerated pace of aging among men and women whose relationships dissolved. More research is needed to identify factors explaining why men who never marry may be at risk for accelerated epigenetic aging while women are not.
