Bioequivalence of a Donepezil/Memantine 10/20 mg Fixed-Dose Combination Versus Single-Component Tablets in Healthy Korean Males.

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
A fixed-dose combination (FDC) tablet formulation of donepezil/memantine (10/20 mg) was developed to improve medication compliance in patients with Alzheimer's disease (AD). This study compared the pharmacokinetic (PK) characteristics and safety profiles of an FDC formulation (donepezil/memantine [10/20 mg]) and single components (SCs) of donepezil (10 mg) and memantine (20 mg). In a randomized, open-label, single-dose, 2-way crossover study, 24 healthy Korean participants received a single oral dose of FDC in 1 period and an SC of donepezil and memantine in another period. For PK analysis, blood samples were collected up to 240 hours after administration. The geometric mean ratios and their 90% confidence intervals for the main PK parameters (C
