Fragmented Ambulatory Care and Medication Count among Older Adults.
Article in American journal of medical quality : the official journal of the American College of Medical Quality. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
This nationwide cross-sectional study explored the relationship between ambulatory care fragmentation and medication use in older US adults, examining variations by chronic conditions and race. Utilizing data from the 2003-2016 REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort study linked with fee-for-service Medicare claims, the authors analyzed care fragmentation (measured by the reversed Bice-Boxerman Index) and medication counts through a 2-week in-person prescription inventory. They employed negative binomial regression, adjusting for potential confounders, and conducted subgroup analyses based on chronic conditions and race. Of the 4524 participants, 40.7% experienced high care fragmentation and 59.8% used 5 or more medications. High fragmentation was associated with a 4% overall increase in medication count ( P = 0.03), a 7% increase for those with 4+ chronic conditions ( P = 0.01), and a 9% increase for Black participants ( P = 0.01). In conclusion, fragmented care is independently associated with greater polypharmacy, particularly among Black older adults and those with multiple chronic conditions.
