European Working Group on Sarcopenia in Older People Algorithm: Step-by-Step Relation With Length of Hospitalization.
Article in Journal of the American Geriatrics Society, 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
backgroundAn international consensus is still lacking on the best operational definition of Sarcopenia in hospitalized older adults. The main objective of this study was to use the EWGSOP2 guidelines in hospitalized old subjects to test its predictivity for adverse clinical outcomes and to evaluate its step-by-step capability to predict unfavorable clinical events. PARTICIPANTS AND
settingThree hundred and seventeen men and two hundred and eighty seven women, aged 65 to 99 years, consecutively admitted to the Department of Geriatrics at the University Hospital of Verona.
methodsAll patients underwent a complete geriatric assessment, clinical evaluation, and for the diagnosis of Sarcopenia, the EWGSOP2 guidelines were applied. As clinical outcomes, length of hospital stay, fall risk, and subjects' quality of life were considered.
resultsAmong 604 hospitalized older patients, 56.0% presented with a SARC-F score suggestive of a risk for Sarcopenia. Patients at risk for Sarcopenia, and with available handgrip strength data, in 85.5% of cases also presented probable Sarcopenia. Among patients with probable Sarcopenia, and with available body composition data, 83.1% were confirmed with Sarcopenia, with a general prevalence of Sarcopenia of 22%. The shortest average length of hospitalization was in non-sarcopenic patients, with a median of 11 days, whereas dynapenic and sarcopenic subjects have respectively a median of 12 and 13 days of hospitalization, with significant differences also after adjustment for age, nutritional status and comorbidity. After dividing the patients into negative or positive for each diagnostic step of the EWGSOP2 algorithm, we found, for each step of the algorithm, a progressively greater association with adverse clinical outcomes.
conclusionsEWGSOP2 algorithm is a valid tool even in hospitalized older patients, and each step enhances the predictivity of the algorithm; however, SARC-F and muscle strength can still be valuable tools for negative clinical outcomes when body composition data are not available.
