Hospitalization outcomes among older adults living undiagnosed or unaware of dementia.
Article in Alzheimer's & dementia (Amsterdam, Netherlands). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionMany persons with dementia are undiagnosed or unaware of dementia, which may affect hospitalization outcomes.
methodsWe evaluated differences in length of stay, days not at home, discharge destination, and 30-day readmissions over 1 year in 6296 older adults in the National Health and Aging Trends Study with linked Medicare claims. Multivariable-adjusted models compared outcomes across no dementia, undiagnosed dementia, unaware but diagnosed with dementia, and aware and diagnosed with dementia.
resultsPersons with undiagnosed dementia had longer length of stay and were more likely to be discharged to a facility (44.8% vs. 19.3%) compared to no dementia; differences persisted in multivariable models. Persons undiagnosed or unaware experienced outcomes similar to persons aware and diagnosed except for more 30-day readmissions in the undiagnosed (adjusted odds ratio [95% confidence interval] 2.05 [1.01, 4.16]). DISCUSSION: Persons undiagnosed or unaware of dementia experience worse hospitalization outcomes, suggesting potential clinically significant implications of unrecognized dementia. Highlights: Persons with undiagnosed versus no dementia have worse hospitalization outcomes.Persons with undiagnosed dementia have more 30-day readmissions compared to persons diagnosed.Lack of clinician or family recognition of dementia may adversely affect hospitalization outcomes.
