Muscle point-of-care ultrasound as a predictor of mortality in older adults with hip fracture.
Article in European geriatric medicine, 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
purposeLower-limb muscle thickness assessed by point-of-care ultrasound (POCUS) is emerging as a prognostic marker in older adults, but evidence in patients with hip fracture is limited. This study aimed to investigate whether POCUS of the vastus lateralis (VL) muscle could predict one-year all-cause mortality in older adults with hip fracture, and to identify the VL thickness cut-off with the highest prognostic performance.
methodsWe conducted a prospective observational study involving patients ≥ 65 years hospitalized for proximal hip fracture at Careggi University Hospital, Florence, Italy, between January 2024 and July 2024 Participants underwent comprehensive geriatric assessment and VL POCUS within 24 h of admission. The study outcome was one-year all-cause mortality. Predictive performance of VL thickness was assessed using ROC curve analysis and multivariate logistic regression.
resultsAmong 154 patients (mean age 86.5 years, 70.1% female), one-year mortality was 42.2%. Mortality was associated with older age, functional and motor impairment, frailty, malnutrition, and higher comorbidity burden. ROC analysis demonstrated good predictive ability of VL thickness (AUC = 0.702), with a cut-off value of < 1.12 cm providing the best discriminative performance (sensitivity 68%, specificity 64%). Patients with reduced VL thickness showed higher mortality (57.9% vs 26.9%, p < 0.001). VL thickness < 1.12 cm independently predicted mortality, after adjusting for age, nutritional status, pre-fracture functional level and comorbidity burden.
conclusionsIn older adults hospitalized for hip fracture, VL thickness of < 1.12 cm independently predicted one-year all-cause mortality, suggesting a potential role of muscle POCUS as a prognostic tool in the orthogeriatric setting.
