Relationship between dementia, COVID-19 risk, and adherence to COVID-19 mitigation behaviors among older adults in the United States.
Article in International journal of geriatric psychiatry, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
objectivesTo examine how dementia is associated with COVID-19 risk and adherence to COVID-19 mitigation behaviors, and whether mitigation behaviors mediate the relationship between dementia and COVID-19 risk. METHODS/
designWe analyzed 2019 and 2020 data from the National Health and Aging Trends Study, a national prospective cohort study of United States older adults age 65+. Outcomes were COVID-19 diagnosis and adherence to COVID-19 mitigation behaviors (handwashing, mask-wearing, and social distancing).
resultsAmong the 3257 older adults in this study, 485 (14.9%) had dementia in 2019 and 98 (3.1%) were COVID-19 positive in 2020. Dementia significantly increased the odds of COVID-19 by 129% (odds ratio [OR] = 2.29, 95% confidence interval [CI] 1.32-3.97), and remained elevated after adjusting for sociodemographics and health (OR = 1.67, 95% CI 0.90-3.11). Dementia significantly decreased the odds of handwashing by 72% (OR = 0.28, 95% CI 0.17-0.44), which remained lower after adjusting for sociodemographics and health (OR = 0.53, 95% CI 0.23-1.21). Dementia was not significantly associated with mask-wearing and social distancing. The relationship between dementia and COVID-19 was primarily mediated by functional impairment, income, and residential setting.
conclusionsDementia was associated with an increased COVID-19 risk and lower adherence to handwashing among U.S. older adults. Adherence to COVID-19 mitigation behaviors did not mediate COVID-19 risk by dementia status. For older adults with dementia, COVID-19 risk could be decreased by prioritizing health interventions.
