Cognitive decline, and quality of life: evidence from community-dwelling older adults in the United Arab Emirates.
Article in Frontiers 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: Cognitive function and quality of life (QoL) are closely linked in older adults, with accumulating evidence suggesting that cognitive performance is an important determinant of overall perceived QoL in older adults. Objectives: To examine cognitive function and its association with multidimensional QOL among adults aged ≥60 years in the United Arab Emirates (UAE) and identify sociodemographic and lifestyle correlates. Methods: A cross-sectional study of 606 community-dwelling older adults from the UAE (55.4% male; mean age 67.2 ± 5.8 years) assessed cognitive function (MoCA) and QOL (OPQoL-Brief). Associations were analyzed using correlation and multiple linear regression (p < 0.05) between the sociodemographic factors and cognitive function (MOCA) to QOL. Results: Participants aged 60-87 years were predominantly Emirati (84.2%), married (77.6%), and living with family (96.7%). Cognitive impairment was present in 69.3% (40.9% mild, 24.8% moderate, 3.6% severe), with the lowest abstraction scores. Mean QOL was 4.21 ± 0.51/5, lowest in social engagement. Cognitive impairment independently predicted lower QOL (β = 0.138; 95%CI: 0.043-0.232; p = 0.001), along with female sex, older age, lower education or income, unmarried status, living alone, and low physical activity. Conclusion: Cognitive function is a key determinant of QOL, supporting integrated, person-centered aging strategies in the UAE.
