The association of frailty with health care costs using the FRAIL scale.
Article in Aging clinical and experimental research, 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
backgroundThe self-reported FRAIL scale is suitable for frailty assessment in the busy primary care practice setting.
aimTo estimate the association between phenotypic frailty assessed by FRAIL and subsequent health care costs in older men and women.
methodsProspective study of 7947 community-dwelling adults (mean age 79.2 years, 52.6% female) enrolled in 4 cohort studies of older adults linked to U.S. Medicare claims. The primary predictor was the FRAIL scale categorized into 3 levels (robust, pre-frail, and frail). A multimorbidity index (Hierarchical Conditions Category score) and the Kim frailty indicator (approximating the deficit accumulation index) were derived from U.S. Medicare claims. Annualized total and sector-specific health care costs (U.S. 2023 dollars) for 36 months after the index examination were ascertained from claims. Generalized linear models with gamma variance and log link functions were used to estimate the association of FRAIL category with subsequent health care costs.
resultsAfter accounting for claims-based indicators of multimorbidity and frailty, estimated annualized mean total health care costs for individuals categorized as robust were $9742 in women and $13,319 in men. Compared with robust individuals, adjusted mean annualized incremental costs for prefrailty were $4104 (95% C.I. 604–5604) in women and $1955 (95% C.I. 102–3808) in men and for frailty were $9028 (95% C.I. 6653–11402) in women and $6604 (95% C.I. 3168–11039) in men. DISCUSSION AND
conclusionPre-frailty and frailty assessed using the self-reported FRAIL scale are associated with higher subsequent total health care costs, even after accounting for claims-based indicators of multimorbidity and frailty.
