Efficacy of 13.3 mg/24 h versus 4.6 mg/24 h rivastigmine patch on activities of daily living in severe Alzheimer's disease.
Article in SAGE open medicine, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveInvestigate efficacy of 13.3 mg/24 h rivastigmine patch in patients with severe Alzheimer's disease on Alzheimer's Disease Cooperative Study-Activities of Daily Living Scale-Severe Impairment Version items and domains.
methodsRetrospective analysis of the 24-week, randomized, double-blind ACTivities of daily living and cognitION (ACTION) study, using factor analysis to establish "best fit" for Alzheimer's Disease Cooperative Study-Activities of Daily Living Scale-Severe Impairment Version items into domains. Treatment differences (13.3 vs 4.6 mg/24 h patch) on items and domains were assessed.
resultsOverall, 632 patients provided Alzheimer's Disease Cooperative Study-Activities of Daily Living Scale-Severe Impairment Version data. Factor analysis yielded four domains. The 13.3 versus 4.6 mg/24 h patch demonstrated significantly greater efficacy on "Daily function" (p = 0.038), supported by greatest effect sizes on items within this domain, and trend toward greater efficacy on "Communication" (p = 0.052). No significant between-group differences were observed on "Independence" (p = 0.600) or "Environment" (p = 0.261).
conclusionThe 13.3 mg/24 h patch was superior to 4.6 mg/24 h patch on "Daily function" in severe Alzheimer's disease.
