Epigenetic aging and lifespan reflect reproductive history in the Finnish Twin Cohort.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Reproductive history is closely linked to health, yet its relationship with biological aging and survival remains uncertain. We investigated this in the Finnish Twin Cohort, a population-based study that enables modeling of full childbearing history while controlling for common risk factors, through questionnaires and civil registries. We model the association between reproductive trajectories and survival in 14,836 women, and assess biological aging in a subset of 1054 participants using the PCGrimAge, an algorithm trained to predict biological aging and mortality risk from DNA methylation. We identify six distinct reproductive trajectories describing different timing and number of childbearing events. Women with the most live births throughout their lives (mean 6.8, SD 2.4) and nulliparous women showed accelerated aging and elevated mortality risk. These findings support the disposable soma theory of aging in modern humans, and provide valuable insights into the genetic and lifestyle-related determinants of lifespan.
