Psychological and functional factors associated with quality of life in comprehensive geriatric care: evidence from a multicenter observational cohort study.
Observational study in BMC geriatrics, 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
backgroundQuality of life (QoL) serves as a central patient-reported outcome but is insufficiently integrated into Comprehensive Geriatric Care (CGC). Although CGC includes a standardized Comprehensive Geriatric Assessment (CGA) to evaluate patient's initial mobility, cognition, depression, and functional impairment, it remains unclear whether it adequately addresses the factors most relevant to QoL.
methodsWe conducted a multicenter observational cohort study including 487 inpatients receiving standardized CGC at three hospitals in Germany. QoL was assessed using the WHOQOL-BREF global items (overall QoL and self-rated health). We examined (1) correlations between the global items and the four WHOQOL domains, (2) interrelations among variables using a regularized partial correlation network with bootstrap stability analysis, and (3) determinants of QoL using multiple linear regression with demographic, clinical, functional and psychosocial factors.
resultsRegression analyses based solely on clinical-functional assessment explained only a small proportion of variance in QoL (adjusted R
conclusionPsychological distress (particularly depressive symptoms, anxiety, loneliness and reduced self-efficacy) was more strongly associated with QoL than traditional clinical-functional variables assessed in the CGA variables among older adults receiving CGC. Routine assessment of psychosocial burden and resources should be integrated into CGC to enable more individualized, patient-centered rehabilitation strategies.
