Prucalopride in Gastroparesis: A Randomized Placebo-Controlled Crossover Study.

American Journal of Gastroenterology, 2019
OBJECTIVES Prokinetics are considered the preferred treatment option for gastroparesis, but evidence of their efficacy is scarce. Prucalopride, a selective 5-hydroxytryptamine 4 receptor agonist used in the treatment of constipation, is able to enhance ...

Crossover studies with survival outcomes

Statistical Methods in Medical Research, 2011
Crossover designs are well known to have major advantages when comparing the effect of two treatments which do not interact. With a right-censored survival endpoint, however, this design is quickly abandoned in favour of the more costly parallel design.

Study of active crossover network

Nigerian Journal of Physics, 2009
An active crossover network system has been realized using an active component LF356 with a JFET input. The net work has two drives, the low frequency drive (Bass) and the high frequency drive (Treble). It employs high level crossover technique. The circuit performance was adequately verified and the frequency response of the system has covered the ...

A study on schema preservation by crossover

Systems and Computers in Japan, 2002
AbstractThis paper considers the combinatorial optimization problem in which the solution (sample) can be decomposed linearly into multiple schemata. Focusing on an arbitrary kind of schema, the schema preservation mechanism of the crossover in the genetic algorithm is discussed from the viewpoint of the increase or decrease of the number of samples ...

The case-crossover study design in pharmacoepidemiology

Statistical Methods in Medical Research, 2009
In the study of the association of transient drug exposures with acute outcomes, the case-crossover design is an efficient alternative to the case-control approach. This design based exclusively on the case series uses within-subject comparisons of drug exposures over time to estimate the rate ratio of the outcome associated with the drug under study.
