Linking health-related behaviors to quality of life in older adults: a latent class analysis.
Article in Innovation in aging, 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 and Objectives: Life expectancy and healthy life years diverge considerably in Austria, and variation in quality of life (QoL) among older people cannot be fully explained by sociodemographic and health-related characteristics. We aimed to identify groups of older adults with underlying behavioral and attitudinal patterns and their associations with QoL. Research Design and Methods: Latent class analysis was performed on cross-sectional data, including QoL (WHOQOL-BREF) from the 2019 Austrian Health Interview Survey (3,995 individuals aged 65+) to identify stable patterns of health behaviors associated with QoL. Variables included lifestyle factors and healthcare use. Class differences were assessed with logistic regression analyses. Results: Four distinct health behavioral classes emerged. Compared with the classes "healthy-consistent-positive" (18%; healthy lifestyle, consistent preventive behavior, positive health system attitudes) and "healthy-inconsistent-positive" (25%; healthy lifestyle, inconsistent preventive behavior, lowest vaccination probabilities, positive health system attitudes), both the class with an unhealthy lifestyle, inconsistent preventive behavior and negative health system attitudes ("unhealthy-inconsistent-negative"; 17%) and the class representing a moderately healthy lifestyle with low physical activities, lower prevention but positive health system attitudes ("moderately healthy-moderately consistent-positive"; 41%) were associated with worse QoL in all domains. Classes also differed in sociodemographic characteristics and activity limitations. Discussion and Implications: Most older Austrian adults were predicted to be in classes with suboptimal health behaviors associated with lower QoL. Interventions should reflect the specific characteristics of these disadvantaged groups. To reach the healthy-inconsistent-positive class, vaccination programs should target younger, healthy-living older adults.
