1 · What the graph read from it

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.

2 · The registry

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 evaluate frequency of use of two anti-dementia drug classes approved for treatment of symptoms, whether populations most likely to benefit are treated, and correlates of treatment initiation.

designNationally representative cohort study.

settingFee-for-service Medicare.

participantsElderly adults with dementia enrolled in Medicare Parts A, B, and D in 2009 (N = 433,559) and a subset with incident dementia (n = 185,449). MEASUREMENTS: Main outcome was any prescription fill for antidementia drugs (cholinesterase inhibitors (ChEIs) or memantine) within 1 year.

resultsTreatment with antidementia drugs occurred in 55.8% of all participants with dementia and 49.3% of those with incident dementia. There was no difference between ChEIs and memantine use according to dementia severity (measured as death within first year or living in residential care vs in a community setting) even though memantine is not indicated in mild disease. In incident cases, initiation of treatment was lower in residential care (relative risk (RR) = 0.82, 95% confidence interval (CI) = 0.81-0.83) and with more comorbidities (RR = 0.96, 95% CI = 0.96-0.96). Sixty percent of participants were managed in primary care alone. Seeing a neurologist (RR = 1.07, 95% CI = 1.06-1.09) or psychiatrist (RR = 1.17, 95% CI = 1.16-1.19) was associated with higher likelihood of treatment than seeing a primary care provider alone, and seeing geriatrician was associated with with lower likelihood (RR = 0.96, 95% CI = 0.93-0.99). Across the United States, the proportion of newly diagnosed individuals started on antidementia treatment varied from 32% to 66% across hospital referral regions.

conclusionAntidementia drugs are used less often in people with late disease, but there is no differentiation in medication choice. Although primary care providers most often prescribe antidementia medication without specialty support, differences in practice between specialties are evident.
