Diagnosis of Alzheimer's disease and related dementias and outmigration of older Puerto Rican Medicare Fee-for-Service beneficiaries, 2012-2019.

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
objectivesThere is limited research on whether receiving a dementia diagnosis could prompt later-life migration, particularly among older Medicare beneficiaries in Puerto Rico. Prior research shows older Puerto Ricans are migrating to the mainland United States, which may include those with an Alzheimer's Disease and Related Dementias (ADRD) diagnosis. This study examined yearly outmigration trends among older Puerto Ricans by exploring their movement patterns in 2011-2019.
methodsWe used data from the Medicare Master Beneficiary Summary File and the Puerto Rican Community Survey and focused on Medicare Fee-for-Service enrollees aged 65 and older. The Chronic Conditions Warehouse algorithm was used to ascertain ADRD diagnosis, and migration was defined as the change of (end-of-year) residence from one year to the next. A linear probability model was used to calculate differences in the rate of outmigration between beneficiaries with and without ADRD.
resultsAcross the study period, the sample averaged 53,294 beneficiaries per year (43,819 [2019] to 66,625 [2012]), with 15% having a previous ADRD diagnosis each year. Overall, older Puerto Ricans previously diagnosed with ADRD were slightly more likely to move to the U.S. mainland compared to those without a diagnosis across the years (adjusted differences of b = 0.14%-0.42%), though differences were statistically significant in some years. For example, outmigration spiked (over 2.5%) among all older adults in the year of Hurricane Maria, regardless of health status. DISCUSSION: Our results suggest that older Puerto Ricans with ADRD are more likely to migrate as they face challenges in aging in place.
