Association Between Nutritional Risk and Physical Function Improvements in Cardiovascular Disease Patients With Frailty in a Community-Based Care Ward.
Article in Circulation 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
Background: We investigated the association between nutritional risk and improvement in physical function during hospitalization among patients with cardiovascular disease, particularly those with heart failure, admitted to a community-based care ward. Methods and Results: We retrospectively analyzed 84 patients who underwent cardiac rehabilitation in a community-based care ward between July 2023 and May 2025. Nutritional risk on admission was assessed using the Mini Nutritional Assessment-Short Form (MNA-SF). Patients were classified into 2 groups: non-malnourished (normal/at risk; MNA-SF ≥8, n=43) and malnourished (MNA-SF ≤7, n=41). The primary outcome was no improvement in physical function (change in Short Physical Performance Battery (SPPB) [∆SPPB] ≤0). Sensitivity analysis used an alternative definition (∆SPPB ≤2). The association between malnutrition and outcome was analyzed using modified Poisson regression adjusted for propensity score. Overall, 21 patients (25.0%) showed no improvement in physical function (∆SPPB ≤0), whereas 53 (63.1%) showed no improvement using the alternative definition. Malnutrition was not associated with no improvement in physical function in the primary analysis (adjusted risk ratio: 1.16; 95% cconfidence interval [CI]: 0.52-2.64; P=0.71), whereas a significant association was observed in sensitivity analysis (adjusted risk ratio: 2.3; 95% CI: 1.19-4.42; P<0.001). Conclusions: Nutritional risk was not associated with no improvement in physical function in the primary analysis, although an association was observed in sensitivity analyses using the alternative definition.
