Longitudinal associations between changes in muscle strength, muscle mass, and physical performance and health-related quality of life in older adults: a four-year analysis from the SarcoPhAge cohort.
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
backgroundSarcopenia, defined by a decline in muscle strength, muscle mass and physical performance, is associated with poorer health-related quality of life (HRQoL) in older adults. However, longitudinal studies investigating this relationship using sarcopenia-specific HRQoL instruments remain scarce.
objectiveTo investigate the association between changes in sarcopenia components and changes in HRQoL over four years using the SarQoL questionnaire, a tool specifically designed for individuals with sarcopenia.
methodsThis study included 333 community-dwelling older adults from the SarcoPhAge cohort, followed annually for four years. HRQoL was evaluated using the SarQoL questionnaire. Sarcopenia components were measured using a handgrip dynamometer to assess muscle strength, dual-energy X-ray absorptiometry (DEXA) to assess muscle mass and the Short Physical Performance Battery (SPPB) test to assess physical performance. Associations between changes in sarcopenia components and changes in global and domain-specific SarQoL scores were assessed using linear mixed models, with random effects to account for within-subject variation.
results333 community-dwelling older adults were included in this study (age: 72.6 years (68.7-77.5), 58.9% women). Over four years, despite an overall age-related decline in sarcopenia components and HRQoL, the increases in physical performance (β = 1.04; p < .0001), grip strength (β = 0.195; p = .0001), and muscle mass (β = 2.47; p < .0001) were independently associated with higher global SarQoL scores. Analyses of the seven SarQoL domains yielded consistent findings.
conclusionThe results support the use of the SarQoL questionnaire as a specific and sensitive instrument for monitoring HRQoL in older adults as it appears responsive to changes in muscle mass, strength, and physical performance.
