Risk of Serious Adverse Events Associated With Individual Cholinesterase Inhibitors Use in Older Adults With Dementia: A Population-Based Cohort Study.
Article in Drugs & aging, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
BACKGROUND AND
objectiveCholinesterase inhibitors (ChEIs) are used as first-line pharmacotherapy to manage dementia. However, there are limited data regarding their relative safety. This study evaluated the risk of serious adverse events (SAEs) associated with individual ChEIs in older adults with dementia and also examined sex-based and dose-based effects on this risk.
methodsThis was a retrospective cohort study using 2013-2015 US Medicare claims data involving Parts A, B, and D. Patients aged ≥ 65 years with a dementia diagnosis and incident use of the ChEIs, namely donepezil, galantamine, or rivastigmine, were included. The primary outcome of interest was SAEs defined as emergency department visits, inpatient hospitalizations, or death within 6 months of ChEI initiation. Multivariable Cox proportional hazards regression with propensity score (PS) as a covariate and inverse probability of treatment weighting generated using generalized boosted models was used to assess the risk of SAEs across individual ChEIs.
resultsThe study included 767,684 older adults with dementia who were incident new users of ChEIs (donepezil 79.42%, rivastigmine 17.67%, galantamine 2.91%). SAEs were observed in 15.5% of the cohort within 6 months of ChEI prescription. Cox regression model with PS as covariate found that patients prescribed rivastigmine (adjusted hazard ratio [aHR] 1.12; 95% CI 1.03-1.33) and galantamine (aHR 1.51; 95% CI 1.24-1.84) were at increased risk of SAEs compared with patients on donepezil. Stratified analyses revealed that rivastigmine was associated with an 18% increased risk for SAEs in females (aHR 1.18; 95% CI 1.06-1.31), and galantamine was associated with a 71% increased risk in males (aHR 1.71; 95% CI 1.17-2.51) compared with donepezil. High and recommended index doses of rivastigmine and galantamine were associated with an increased risk of SAEs compared with donepezil. The findings were consistent in sensitivity analyses.
conclusionThe study found that the risk of SAEs varied across individual ChEIs, with sex and dose moderating these effects. Therefore, these moderating effects should be carefully considered in personalizing dementia care.
