Dementia Diagnosis Unawareness and Caregiver Burden in a Multi-ethnic Cohort.
Observational study in Journal of general internal medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03403257 (Brain Attack Surveillance in Corpus Christi--Cognitive), which is not on this 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.

Abstract
backgroundPrevious reports suggest patient and caregiver lack of awareness of dementia. Little is known about how this varies by ethnicity and how informal (family) caregiver burden is associated with knowing a dementia diagnosis.
objectiveTo investigate whether participants with probable dementia were aware of a diagnosis provided by a physician and how this differed among Mexican American and non-Hispanic White participants; whether having a primary care physician was associated with dementia diagnosis unawareness; and the association of dementia diagnosis unawareness with caregiver burden.
methodsThis was a population-based cohort study in Nueces County, Texas. Participants who scored less than 20 on the Montreal Cognitive Assessment (MoCA) were classified as having probable dementia. Diagnosis unawareness was defined as participants with probable dementia who had not been told that diagnosis by a healthcare provider. Logistic regression models examined the association of ethnicity and dementia diagnosis unawareness. A negative binomial regression was used to assess the association of dementia diagnosis unawareness and caregiver burden.
resultsEighty-one percent of eligible participants were not aware of a dementia diagnosis. Mexican American participants (MAP) were more likely to be unaware of a diagnosis (85%, 95% CI 81-89%) than non-Hispanic white participants (NHWP) (68%, 95% CI 58-75%). Only 6.6% of the participants with probable dementia had no primary care provider, with no observed association between diagnosis unawareness and lack of primary care. Diagnosis unawareness was not associated with caregiver burden (IRR = 0.93, 95% CI 0.77-1.14) but was associated with lower MoCA score (IRR = 0.98, 95% CI 0.96-1.00) and greater physical impairment (IRR = 1.06, 95% CI 1.03-1.10).
conclusionDementia diagnosis unawareness was very high in this community. MAPs are more likely to be unaware of a diagnosis than NHWPs. Lack of access to primary care and caregiver burden were not associated with dementia diagnosis unawareness.
