Three-time-point directional patterns of frailty and physical function in older adults participating in community gathering places in Koshigaya City, Japan: a retrospective exploratory study.
Article in Preventive medicine reports, 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
Objective: Community gathering places (Kayoinoba) promote social participation and may help prevent frailty among older adults. This exploratory study examined three-time-point trajectories of frailty and physical function and whether baseline multidimensional information helped distinguish favorable long-term trajectories. Methods: This retrospective longitudinal study used municipal assessment data from Kayoinoba sites in Koshigaya City, Japan, collected at baseline (September 2016-October 2019), approximately 6 months later (March 2017-October 2020), and at the fiscal year 2022 municipal evaluation, conducted between August 2022 and November 2023. Outcome-specific samples included Kihon Checklist (KCL) total score ( Results: Outcomes showed heterogeneous longitudinal patterns. CS-30 had the highest LongGood (51.00%) and ImproveMaintain (38.00%) rates. TUG had the lowest LongGood rate (27.03%) and frequent ImproveRebound (37.84%) and ConsistentDecline (28.38%) patterns. Domain-score models showed numerically higher apparent areas under the receiver operating characteristic curve for several outcomes, but optimism-corrected estimates were attenuated. Conclusions: Frailty and physical function showed heterogeneous, outcome-dependent directional patterns. Findings are descriptive and hypothesis-generating, not causal evidence of Kayoinoba effectiveness.
