Long-term impact of a senior volunteer-driven frailty check programme on care dependency and expenditures: a 10-year population-based cohort study in Japan.
Article in Age and ageing, 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
backgroundAlthough volunteer-driven, community-based interventions to prevent long-term care (LTC) dependency have shown promise, long-term evidence of their effectiveness and economic impact remains scarce. We aimed to evaluate the association of a volunteer-driven frailty check (FC) programme with LTC certification and benefit expenditures.
methodsWe conducted a 10-year retrospective, population-based cohort study in a municipality in Japan. Of 59 812 residents aged ≥65 years (2015-2024), FC participants were matched 1:1 with non-participants separately within each year using propensity scores, and the yearly matched sets were pooled for analysis, yielding 2672 participants and 2672 matched controls. Outcomes were incident LTC certification and annual per-capita LTC expenditures, analysed using Cox proportional hazards and generalised linear mixed-effects models.
resultsAmong 5344 matched individuals (mean age 73.5 ± 4.9 years), 16.8% of participants and 19.8% of controls received LTC certification [hazard ratio 0.85, 95% confidence interval (CI) 0.75-0.97; absolute risk reduction 3.0%; number needed to treat 33]. Annual per-capita LTC expenditures were consistently lower among participants, with the gap widening over time (cost ratio 0.66, 95% CI 0.51-0.84), yielding cumulative savings of ~JPY443 000 per participant over 10 years. Exploratory analyses indicated slower growth in combined medical and LTC expenditures.
conclusionThis programme was associated with lower LTC dependency and slower growth in combined medical and long-term care expenditures. Implemented in 106 municipalities in Japan, this volunteer-led, community-based model may offer a low-cost, scalable intervention to promote healthy ageing and sustainability in super-aged societies, with relevance for countries facing population ageing and fiscal constraints.
