Article in Primary care companion to the Journal of clinical psychiatry, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00305903 (A Prospective, 26-Week, Open-Label, Multi-Center, Single-Arm Pilot Study to Evaluate the Safety and Tolerability of Rivastigmine Capsule With Add on Memantine HCl in Patients With Probable Alzheimer's Disease), which is not on this map.

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.

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.

Abstract

objectiveTo evaluate the long-term safety, tolerability, and efficacy of 2 strategies for switching from donepezil to rivastigmine transdermal patches in patients with mild to moderate Alzheimer's disease.

methodThis was a prospective, 25-week, randomized, open-label, parallel-group study to evaluate an immediate or delayed switch (7-day withdrawal) from donepezil (5 to 10 mg/d) to rivastigmine transdermal patches (4.6 mg/24 h). Participants included male and female patients, aged ≥ 50 years, with a DSM-IV-TR diagnosis of mild to moderate dementia of the Alzheimer's type, defined as a Mini-Mental State Examination score of 10-24, inclusive. Patients were enrolled between February 2007 and February 2008. The study was split into a 5-week core phase and a 20-week extension phase. Safety and efficacy results from the extension phase are presented.

resultsBoth switching strategies were well tolerated. Rates of discontinuation for any reason were similar between the groups. Discontinuations due to adverse events were also similar, and the incidence of gastrointestinal adverse events was low. Apart from Alzheimer's Disease Cooperative Study-Activities of Daily Living Scale scores, at the end of the study, there was no statistically significant change from baseline in cognitive, behavioral, or global outcomes. Over half of the patients preferred rivastigmine transdermal patches to a tablet.

conclusionsThis study suggests that the majority of patients receiving donepezil tablets can be safely switched to rivastigmine transdermal patches without significant deterioration in cognition, behavior, and global functioning.
