Rebalancing health investment across the life course: a high-value age segments framework for aging societies.
Article in Frontiers in public 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
Health systems in rapidly aging societies continue to direct a disproportionate share of expenditure toward reactive, late-life care, despite evidence that earlier and mid-life investment can generate substantial long-term population health returns. High-Value Age Segments (HVAS) are proposed as a life-course framework for prioritizing health investment according to differences in marginal returns across age groups. Three broad periods are identified: early life from the fetal stage to approximately age 25, mid-adulthood from ages 26 to 55, and later adulthood from age 56 onward. Early-life interventions are associated with durable gains in health and human development, mid-adulthood interventions with delayed chronic disease onset and preserved productivity, and later-life interventions with reduced morbidity and maintenance of functional capacity. Embedding HVAS within policy frameworks may support more efficient and sustainable allocation of health resources under demographic aging.
