Prognostic Value of Frailty Assessment Combining the Frailty Index Based on Laboratory Tests With the Clinical Frailty Scale in Patients With Acute Heart Failure.
Observational study in Journal of the American Heart Association, 2025. 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
backgroundHeart failure (HF) is often complicated by frailty. We evaluated the prognostic value of the Frailty Index based on laboratory tests (FI-lab) and the Clinical Frailty Scale, as well as their combined use, for adults with acute HF.
methodsThis study was a post hoc analysis of the POPEYE-AHF (Prospective Observational Study on Acute Pharmacotherapy and Prognosis in Management of Acute Heart Failure) registry, a prospective observational study evaluating the treatment and characteristics of patients with acute HF. At discharge, 975 patients had available FI-lab data, while 637 patients had available Clinical Frailty Scale data. The FI-lab was determined at discharge by the proportion of 21 laboratory items with abnormal results. The outcomes were all-cause death, HF hospitalization, and the composite of both.
resultsAt baseline, the median age was 80 years, and 45.0% of the patients with FI-lab data were women. Multivariable Cox proportional hazards regression revealed that the measured FI-lab was associated with all outcomes (all-cause death: hazard ratio [HR], 1.38 [95% CI, 1.15-1.67],
conclusionsFI-lab identified high-risk adults with acute HF. The combined use of the Clinical Frailty Scale and FI-lab identified adults at high risk of all-cause death.
